Authors: Sanches Alex Guimarães , Pedrosa Vanessa Maria Dantas , Silva Maryelle Barros da , Fernandes Thiago Feliph Silva , Teixeira Gustavo Henrique de Almeida
Published: August 2021

ABSTRACT Pera-do-cerrado (Eugenia klotzschiana O. Berg) has a good appearance and adequate post-harvest shelf life. However, little information is available regarding its maturity stages. This study aimed at characterizing E. klotzschiana fruits harvested at three maturity stages (immature, physiological mature and ripe), in addition to evaluating the physical and chemical changes during storage at ambient temperature (24 ± 2 ºC and 75 % ± 5 % of RH) for up to 5 days. The ripe fruits had a higher fresh mass (98.03 g), width (5.61 cm) and ratio (5.37), and lower titratable acidity (1.27 %). In contrast, immature fruits showed a greener peel (101.32 ºh) and higher vitamin C content (11.23 mg 100 g-1). There was an increase in the fresh weight loss (3.05 %) and a decrease in the peel luminosity (67.09-57.12 L*) and vitamin C content (8.11-5.04 mg 100 g-1). However, the soluble solids (SS) values did not change during the 5 days of storage. A reduction in the titratable acidity (TA; 1.29-1.06 %) was also observed, which resulted in a higher ratio (3.81-5.84). In conclusion, E. klotzschiana fruits should be harvested ripe, as they present larger dimensions, better color, higher SS/TA (flavor) and are less acidic.

OMAGUAS CREPUSCULARES: IDENTIDAD Y ACULTURACIÓN DE UN PUEBLO AMAZÓNICO (SIGLOS XVII, XVIII Y XIX)
Authors: Miret Ferran Cabrero
Published: August 2021

El presente estudio visibiliza los cambios producidos en la cultura omagua de la Amazonia durante la Colonia y los primeros años republicanos, a través del análisis del proceso de colonización sufrido por esta. Toma como base una revisión crítica de textos pertenecientes a los siglos XVII, XVIII y XIX. Se emplean, además, dos conceptos clave en ciencias sociales: identidad y aculturación. Las fuentes etnohistóricas de las misiones o provincia de Maynasa extensa zona de selva otorgada por la Audiencia de Quito) resultan valiosas para comprender lo que desde el siglo XVII se conoce como cultura omagua y su consecuente naturaleza como nación, en el sentido de conciencia de identidad cultural unitaria y movilizada políticamente frente a otros. Aunque los omaguas de principios del siglo XVII ocupan un territorio que pareciera mayor al citado en las primeras crónicas, a fines del mismo la colonización provoca aumento de conflictos, debacle poblacional, desestructuración social y ocaso cultural.
Bottom-supported tension leg towers with inclined tethers for offshore wind turbines
Authors: Ishtiyak Mohammed , Sarkar Arunjyoti , Fazeres-Ferradosa Tiago , Rosa-Santos Paulo , Taveira-Pinto Francisco
Published: August 2021

Offshore wind with high energy density and low turbulence has attracted the global scientific community towards the development of the Offshore Wind Turbines (OWTs). Today, most of the shallow water sites are already occupied, and the industry is looking to install turbines at the deep water sites (water depth > 50m). However, an OWT support structure designed with the conventional concepts becomes massive and expensive in deeper waters. In contrast, floating OWTs are more expansive than the bottom supported ones, and considered suitable for a water depth of 60 m or more. A novel support structure concept termed a ‘bottom supported tension leg tower’ (BSTLT) has been proposed recently and the possibility of using bottom supported structures in deeper waters is shown. In this paper, an extension of the BSTLT concept has been achieved using inclined tethers with a monopile. The preliminary technical feasibility including the sensitivity of the natural frequencies and dynamic analyses considering the in-place operating and the extreme design conditions has been studied for 50 m water depth. The results show that the proposed concept can be utilized to make the monopile based support structures more cost-efficient for the water depth stated above.
Assessing landscape design of small towns in Russia
Authors: Karandeev Alexander , Sedykh Olga , Yartseva Elizabeth
Published: August 2021

The article deals with issues related to the urban design assessment of a small towns in the Lipetsk Region. The creation of a comfortable living environment is one of the most important functions of urban landscapes' ecosystem. This paper explains a methodology of assessing the urban public spaces using three-dimensional mapping, data collected through remote sensing and field research as well as questionnaire that included a comprehensive score. The score description contains an auxiliary category that helps assigning the grade of the score. A methodology for describing towns’ landscapes, developed on the basis of a questionnaire is applied. The authors adhere to the requirement of landscape factors equivalence as one of the provisions that determine landscape design. Research studies have shown that according to the total assessment score, the level and quality of urban landscape design are highly appreciated by residents. Parks and public green areas are a key link in the sustainable development of urban areas and they are not included in the general territory of small towns and are located on small land plots. Why is this the case? The landscape design of small towns in Russia is poorly studied and its scientific assessment requires further development.

Authors: NJIE Ebrima J. , MEMİŞ Nurcan , ÖZDAMAR Cihat , DEMİR İbrahim
Published: August 2021

This research was conducted to investigate the efficacy of charcoal and ash in maintaining the quality of lettuce, cabbage, onion, pepper and carrot seeds during storage. The seeds were stored over charcoal and ash at a seed/material ratio of 1:1 and stored at room temperature (20°C) and at 35°C for 24 months. The control seeds were dried to between 5-6% seed moisture content and stored in hermetic packets at -20°C. Samples were collected from storage after 6, 12, 18, and 24 months and subjected to a germination test and ageing test at 45°C for 72 hours using 72% saturated sodium chloride (NaCl) solution. There was no difference between the seed viability for the controls and treatments after 6-12 months at 20 and 35°C between the two storage methods. However, seed quality declined at 18 months and 24 months. This was seen in lettuce, onion and carrot seeds more than pepper and cabbage at both storage temperatures. Similarly, seed vigour also reduced with extended storage to 18 and 24 months. Results showed ash and charcoal can be used to maintain seed quality over 12 months even at 35°C.
Memoria y percepción en la entrevista autobiográfica: una simulación episódica que se adapta en tiempo real al contexto
Authors: Guerrero Velázquez Carlos Alberto
Published: August 2021

Normalmente se piensa en la percepción y la memoria como dos capacidades independientes, creyendo que la primera solo tiene influencia sobre la segunda durante la codificación. En las entrevistas autobiográficas de historia oral y memoria histórica, los entrevistados seleccionan, adaptan y completan sus recuerdos para crear diferentes versiones de ellos. En este artículo se argumenta que lo anterior es consecuencia de la naturaleza simulativa de la memoria episódica, y del empleo por los entrevistados de información perceptiva para generar y adaptar sus recuerdos a un discurso autobiográfico, buscando satisfacer un propósito comunicativo. Para ilustrar esto, se analizan tres factores contextuales que influyen sobre la construcción del recuerdo en una entrevista autobiográfica (objetivo comunicativo, idioma de comunicación e interacción emocional), mostrando que, en este tipo de recuperación, memoria y percepción contribuyen simultáneamente a construir simulaciones de eventos que se adaptan en tiempo real al contexto donde ocurre la evocación.
What makes a mental state feel like a memory: feelings of pastness and presence
Authors: Rosen Melanie , Barkasi Michael
Published: August 2021

The intuitive view that memories are characterized by a feeling of pastness, perceptions by a feeling of presence, while imagination lacks either faces challenges from two sides. Some researchers complain that the “feeling of pastness” is either unclear, irrelevant or isn’t a real feature. Others point out that there are cases of memory without the feeling of pastness, perception without presence, and other cross-cutting cases. Here we argue that the feeling of pastness is indeed a real, useful feature, and although this feeling does not define memory ontologically, it is a characteristic marker which helps us easily categorise a mental state first-personally. We outline several cognitive features that underlie this experience, including the feeling of past accessibility, ergonomic significance, immersion, objectivity and mental strength. Our account is distinctly phenomenal, rather than doxastic, although our web of beliefs may contribute to this experience.
Causation and mnemonic roles: on Fernández’s Functionalism
Authors: Andonovski Nikola
Published: August 2021

Debates about causation have dominated recent philosophy of memory. While causal theorists have argued that an appropriate causal connection to a past experience is necessary for remembering, their opponents have argued that this necessity condition needs to be relaxed. Recently, Jordi Fernández (2018; 2019) has attempted to provide such a relaxation. On his functionalist theory of remembering, a given state need not be caused by a past experience to qualify as a memory; it only has to realize the relevant functional role in the subject’s mental economy. In this comment, I argue that Fernández’s theory doesn’t advance the debate about memory causation. I propose that this debate is best understood as being about the existence of systems, which support kinds of interactions that map onto the relations dictated by (causal) theories. Since Fernández’s functionalism tells us very little about this empirical question, the theoretical gains from endorsing it are minimal.
Fernández, J. (2019). Memory: a self-referential account. Oxford University Press
Authors: Álvarez Céspedes Juan Fernando
Published: August 2021

Fernández’ most recent book constitutes an articulated development of several philosophical considerations on memory displayed in previous, and forthcoming publications. The result of such articulated development ends up being a consistent account that provides an innovative and thought-provoking perspective on episodic remembering. This volume not only gathers and articulates the author’s previous ideas, but also provides new reflections, and objections that encompasses four significant domains in the philosophy of memory. In the first part of the book (Chapters 1, 2, and 3), Fernández offers an account of both the metaphysics and the intentionality of episodic memory; in the second part (Chapters 4 and 5), the author deals with certain phenomenological aspects involved in remembering; in the third part (Chapters 6 and 7), two important debates in the epistemology of memory are discussed.
Tendencias del financiamiento público y dilemas de la política educacional chilena (1999-2018)
Authors: Donoso-Díaz Sebastián , Arias-Rojas Oscar , Reyes-Araya Daniel
Published: August 2021

Se expone la evolución del presupuesto público chileno en educación en el presente milenio, atendiendo su relevancia como componente clave del desarrollo, e indagando sobre lo que ello significa en referencia con la evolución del Producto Interno Bruto (PIB) del país, como también del presupuesto público total. Las partidas presupuestarias son actualizadas y analizadas en el contexto de algunos hitos claves de las políticas educativas del período estudiado. Los principales resultados muestran incrementos importantes del presupuesto, incluso por sobre el crecimiento del PIB, acordes con las demandas sociales en este campo. No obstante, se estima que deben realizarse algunos exámenes detallados, pues no se puede continuar con un presupuesto sectorial que crece ilimitadamente, sino también se requiere de otras formas de asignación presupuestaria que impliquen un cambio estructural. Los hallazgos evidencian la importancia de avanzar en estas materias para sustentar aquellas políticas estratégicas que Chile no resuelve satisfactoriamente: segmentación social del sistema escolar, desigualdad social y baja calidad de resultados educativos.
Poder de mercado y transmisión asimétrica de precios en Chile: el caso de la carne bovina y porcina
Authors: Troncoso Sepúlveda Ricardo Andrés
Published: August 2021

Este artículo examina el efecto del poder de mercado sobre la transmisión de precios productor-mayorista en las industrias de carne bovina y porcina chilena. Se utilizaron elasticidades conjeturales para representar el poder de mercado y se estimó un modelo de corrección de errores por umbral (TECM, por sus siglas en inglés) con tres regímenes para distinguir el comportamiento de ajuste de precios con relación al equilibrio de largo plazo. Los resultados indican que el poder de mercado tiene impacto significativo en el sector bovino cuando los precios se hallan en fase decreciente. En dicha fase, los mayoristas pueden ejercer poder de mercado para ralentizar el ajuste de precios y conservar márgenes de ganancia mayores durante más tiempo. La hipótesis de simetría de largo plazo es rechazada en el sector bovino cuando se incorpora el poder de mercado y no rechazada cuando se ignora en la especificación del modelo, sugiriendo transmisión asimétrica entre los regímenes bajo y alto. Este resultado, refuerza la idea que el poder de mercado mayorista produce asimetrías en el ajuste de precios que son régimen-dependientes sólo en el sector bovino.
La posición cíclica de la política fiscal en Colombia durante el periodo 1990-2015
Authors: Portillo Riascos Luis Hernando
Published: August 2021

Este artículo busca determinar la posición cíclica de la política fiscal en Colombia durante el periodo 1990-2015. Para este propósito, se utilizan tres variables: el gasto del gobierno, el déficit fiscal ajustado cíclicamente y la deuda pública. Como resultado de este ejercicio, se concluye que la política fiscal en Colombia mostró una posición procíclica y asimétrica, lo que quiere decir que esta herramienta de política económica actuó como un mecanismo desestabilizador de la demanda agregada y contribuyó así a amplificar los efectos generados por los ciclos externos. Por componentes del gasto, la variable con un sesgo mucho más marcado por el ciclo económico fue la inversión pública.
Prediciendo la llegada de turistas a Colombia a partir de los criterios de Google Trends
Authors: Correa Alexander
Published: August 2021

Este artículo examina si los criterios de búsqueda de Google Trends son útiles para predecir la llegada mensual de turistas a Colombia. Para este fin, se compara un modelo base que utiliza como predictor los rezagos propios de la llegada de turistas con dos especificaciones alternativas: (i) el modelo base aumentado con la inclusión de datos mensuales de Google Trends; y (ii) el modelo base, pero modificado con la inclusión de datos semanales de Google Trends. Los resultados obtenidos presentan evidencia estadísticamente significativa de que los datos de Google Trends aportan beneficios a la evaluación y predicción de llegadas de turistas a Colombia. En particular, se encuentra que datos de alta frecuencia (semanales) agregan alto valor predictivo en comparación con los modelos que usan datos de la misma frecuencia (mensuales). De este modo, la industria del turismo y los encargados de la política pública de turismo pueden apoyarse de la capacidad predictiva de los datos de Google Trends para mejorar sus procesos de planeación en el corto y mediano plazo.
Simulazione e dissimulazione a sostegno di politica e amore sullo sfondo della trattatistica del Cinquecento
Authors: Valentino Gennaro
Published: August 2021

Si propone l’analisi di due costituenti rinascimentali ben approfonditi nella precettistica e trattatistica del Cinquecento: la simulazione e dissimulazione. Attraverso lo studio di alcuni trattati precettistici, riflettiamo non solo sul fatto che nel Cinquecento queste pratiche comportamentali fossero riconducibili alla sfera dell’esteriorità, ma ragioneremo anche sul fatto che esse, mutuate dalla politica, si riversassero nella vita privata dell’individuo aiutandolo a raggiungere la «felicità amorosa», per dirla come Piccolomini. Si tenta di tracciare il fil rouge che collega gli scritti politici di Machiavelli e Guicciardini con La Raffaella, di Piccolomini, mettendo in luce gli obbiettivi conseguibili attraverso l’uso di tali pratiche comportamentali.

Pragmatism and the Limits to the European Parliament’s Strategies for Self-Empowerment
Authors: Closa Montero Carlos , González de León Felipe , Hernández González Gisela
Published: August 2021

Despite the European Parliament’s (EP) growing role, its influence and scrutiny capacity remain considerably weaker than the role traditionally reserved for parliaments in economic and fiscal policy decision-making at the national level. The EP has exploited any opportunity to enhance these powers: In particular, the EP has a record of using crisis and extraordinary situations to expand its role beyond the formal prerogatives given to the institution. Following this literature, this article examines the role and influence of the EP on economic and fiscal policy, focusing on the response to the Covid-19 crisis. Negotiation of the Recovery and Resilience Facility presents an auspicious area to analyse the strategies implemented by the EP to influence the outcome and reinforce its position in EU economic governance. The article will look specifically at the formal and informal mechanisms used by the EP during the crisis to expand its powers. Moreover, it utilises a research design that combines the content analysis of several official/public documents and statements from key members of the European Parliament (MEPs) involved in economic policy.
Parliamentary Scrutiny of the European Semester: The Case of Poland
Authors: Schweiger Christian
Published: August 2021

The European Semester became an essential part of the revised governance architecture of the Europe 2020 reform strategy for the Single European Market under the conditions of the global financial crisis and the emerging eurozone crisis a decade ago. The article examines to what extent the European Semester offers channels to establish throughput legitimacy by granting national parliaments the ability to effectively scrutinise executive decision-making in the annual policy cycle. Poland is chosen as the case study for parliamentary scrutiny of the EU’s system of multi-level governance in the East-Central European region. The analysis adopts a liberal intergovernmentalist two-level approach. On the domestic level it concentrates on the involvement of the Sejm, the lower house of parliament, on the drafting of the Polish National Reform Plans for the annual Semester policy cycle between 2015 and 2020. The basis for the analysis are official transcripts from the plenary debates in the relevant committees, the European Affairs Committee and the Public Finance and the Economic Committee. The Polish case study illustrates that the European Semester represents a predominantly elite-driven process of policy coordination, which is strongly geared towards EU-level executive bargaining processes between national governments and the European Commission at the expense of domestic parliamentary scrutiny.
Correctional and Developmental Program of Spiritual and Moral Education and Development of Primary General Education of Hearing-Impaired and Late-Deaf Students «Along the Roads of Little Parables»
Authors: Petrukhina N.A. , Mazurenko T.B. , Martynova O.V.
Published: August 2021

The program belongs to the correctional and developmental direction. In this particular version, the program is aimed at ensuring the spiritual and moral development of hearing-impaired and late-deaf students at the stage of primary general education using digital educational resources. One of the most important principles in teaching children with hearing impairments is the principle of clarity and dosed educational material. First of all, it involves the construction of the educational process based on specific objects, images, actions and small texts that are directly perceived by them. The motivational moment in training is no less important. It is important to give the child not a name for this or that concept, but to form an understanding of the information received and teach how to use the knowledge gained in everyday activities. Thus, all the functions of the learning process for hearing impaired children can be successfully implemented only if they rely on scientific data on the characteristics of the mental development of deaf students and create conditions for purposeful work to ensure this development. It should be borne in mind that the additional (correctional) goals of education for the hearing impaired and the specificity of their cognitive activity (perception, speech, thinking) determine a number of distinctive features that characterize the learning process. This program is the most accessible for use in working with hearing impaired children, as it is based on visual con-tact, which allows you to convey information to hearing impaired children in a more accessible form, in the upbringing of the spiritual and moral qualities of their personality, which helps to improve the listening comprehension of short texts.

Authors: Soboleva M.V.
Published: August 2021

The program is correctional and developmental, aimed at the development of cognitive processes in children of senior preschool age 5.5–7 years old, including those with disabilities, during the period of preparation for school. It is designed to ensure the successful mastering of the prerequisites of educational activity through the development of cognitive processes, curiosity, the formation of cognitive interests and actions, as well as the skills of communicative activity in a group of peers. The program is focused on creating a unified educational environment, where active participants in the educational and educational environment are not only children, but also teachers and parents. The formation and development of cognitive interest requires the creation of favorable psychological and pedagogical conditions, and the search for effective means that will not only develop the child’s mental processes and creative abilities, but also strengthen his faith in his own strengths and capabilities, develop self-esteem, which, in his the queue can become a resource for successful adaptation to school. The skill of the teacher at this stage should be manifested in the ability to choose suitable play tools and methods for solving cognitive tasks and tasks in such a way that preparing for school becomes not a routine activity, but a useful and exciting game.

Authors: Suvorina N.P.
Published: August 2021

The article deals with the research on the problem of blind and visually impaired teenagers’ psycho-logical correction, development and formation of self-construction. Optical defect influences personality development. Problems of personality formation are inseparable from the questions of social adaptation of children with profound visual impairment. The important aspect of adaptation is personality adaptation to his inner self. In the native and foreign scientists’ works, there are few re-searches on social adaptation and personality formation where the questions of blind and visually impaired personalities’ socialization and formation would be studied. The aim of the work is formation of positive self-construction within blind and visually impaired teenagers as a social adaptation factor through creating and testing of remedial programmes. The article gives the results of the research, conducted in two stages. With the aim of correcting, formation and development of teen-agers’ personality sphere, some remedial programmes were worked out. Positive dynamics demonstrates the effectiveness of remedial programmes on the formation of complex and positive self-construction as a factor of successful social adaptation, successfully implemented in Verkhnepyshminskaya School for five years.

Personnel Identification System Using the Wireless Channel Characteristics and Machine Learning
Authors: Jie Zhao, Yong Li,
Published: August 2021

In the presence of a Wi-Fi network, movements of individuals lead to changes in the channel state information (CSI) of the Wi-Fi network. Thus, it is possible to use CSI to identify specific individuals based on walking gait and under movements. We have built a hardware system to collect CSI and developed CSI real-time acquisition and visualization software. We further improve results by preprocessing the CSI to remove noise by outlier removal, a low-pass filter, and a discrete wavelet transform. For identity recognition, we propose a parallel learning structure using a convolutional neural network (CNN) and bidirectional long-term and short-term memory network to extract amplitude and time sequence features of human gait at the same time. We then classify the two gait features using Softmax function to identify individuals. Our identity recognition experiment with 30 people yielded a maximum accuracy of 98.7% with our device and software. The system has a value of application in the field of smart home and intrusion detection.
The Optimization Model of Composite Material UAV Shooting Flight Routes
Authors: Zheng Ting
Published: August 2021

UAV is one of the important achievements of scientific and technological innovation, which has been widely used in various fields of life in recent years. UAVs of composite materials are the most popular because the composite itself has designability, and can be optimized according to the strength and stiffness of the aircraft without changing the structural weight. In order to ensure the UAV to carry out more accurate image acquisition under the actual ground conditions, through the analysis of decision variables, this paper uses the linear weighting of image shooting range and pixel accuracy to establish the objective function, and establishes the optimal shooting angle under different constraints Considering the actual motion characteristics of objects such as automobiles, this paper assumes that the tracked ground targets are a class of motion objects with non-integrity constraints when the flight altitude of UAV is fixed and the flight speed is constant. The ground target model and the flight dynamics nonlinear model are established. This paper presents a new RRT* algorithm for path planning based on the obstacles encountered by UAV during flight, that is, using the cost function to select the node with the minimum cost in the field of expanding nodes as the parent node, using the MATLAB to select a reasonable obstacle avoidance strategy, the global optimal route is obtained by smoothing processing, and the data simulation test is carried out. The experimental results show that the model is robust.

Improved Relative Range Equation in Squint SAR for Moving Targets Refocusing
Authors: Jie Chen Pu Cheng, ZhentaoYu,
Published: August 2021

Moving target detection is difficult for synthetic aperture radar (SAR). As SAR is designed for imaging of stationary ground scene, the moving targets would be blurred and displaced in conventional SAR imaging. To increase the signal clutter ratio, the moving targets should be refocused while detecting. Based on relative range equation, one can refocus and detect the moving targets simultaneously by searching the relative velocity. This method has been derived and applied for side looking SAR. In this paper, we extend the relative range equation to squint mode. The procedures of the refocusing method are also illustrated. By introducing a parameter of relative squint angle, the imaging position of the moving target is derived. The refocusing method is validated by simulations. The moving target can be optimally refocused, and the refocused position can be parametrized by the relative motion parameters.

Linear Econometric Estimations of the Effects of Religious Beliefs on Pro-environmental Behaviors
Authors: Gang Li Yunrong Li,
Published: August 2021

Environmental protection has become a public concern as the economy grows, especially in developing countries. Previous studies have examined determinants of individual pro-environmental behaviors. Using data from a nationwide survey carried out in mainland China in 2013, we intend to estimate the effects of religious beliefs on individual pro-environmental behaviors. We employ a linear econometric model and apply an Ordinary Least Square estimator to estimate the model. We use five measures to represent pro-environmental behaviors and distinguish between plain and strong religious beliefs. Estimation results show that, in general, holding any religious belief has a significant impact on all types of pro-environmental behaviors. Moreover, strong religious beliefs have greater impacts on different types of pro-environmental behaviors. Policy implications of the paper could be that people with religious beliefs should not be the target of programs aiming at promoting individual pro-environmental behaviors.
Innovative Practice and Promotion Countermeasures of Micro-major in Chinese Universities
Authors: Jun Dai Huaide Wen,
Published: August 2021

Traditional talent training at universities can no longer meet the changing needs of talents brought about by rapid social and economic development. A more flexible, faster, and lower-cost talent training method of micro-majors is gradually introduced into the practice of talent training at universities. Micro-major has become an important means to make up for the lagging of majors setting at universities and a supplement to increase the supply of talents in emerging industries. The micro-major curriculum system simplifies theoretical teaching and emphasizes applied practice, which is conducive to better social training. Online and offline teaching methods are generally adopted, and the school-enterprise cooperation model is introduced, which alleviate the shortage of teachers for talent training in emerging industries to a certain extent. However, the development of micro-majors also needs to improve the actual effect of practical teaching, strengthen the construction of dual-qualified and dual-capable teacher teams, and take into account the relationship between micro-majors and general majors.
Nonlocal Mean Filtering Algorithm for Low Contrast Images and its Application
Authors: Guan Tianyi
Published: August 2021

High background noise, cracks, fuzzy boundaries image containing the chromatism, etc are the common problems faced in the low contrast image recognition, this paper takes the core fracture identification of two-dimensional section as an example, and highlight the point, simplify the problem, this paper only considering the three dimensional images of two-dimensional cross section along the direction perpendicular to the core shaft, focusing on the identification of disc core cracks within the dark grey. Each voxel based on 3D digital images corresponds to a gray value. The smaller the value, the blacker the corresponding voxel will be. The larger the value, the whiter the corresponding voxel is. By fine-tuning the background color difference, filtering and denoising, marking the non-crack area, secondary denoising by graphics method and other algorithm methods, the identification efficiency of the crack area in the two-dimensional cross-section diagram of the core column is effectively improved. This method can also be used as a solution to other problems in similar scenes.
