Methods to Increase the Contrast of the Image with Preserving the Visual Quality
Authors:   Lviv Polytechnic National University, Maksymiv Mykola , Rak Taras
Published: January 2022

Contrast enhancement is a technique for increasing the contrast of an image to obtain better image quality. As many existing contrast enhancement algorithms typically add too much contrast to an image, maintaining visual quality should be considered as a part of enhancing image contrast. This paper focuses on a contrast enhancement method that is based on histogram transformations to improve contrast and uses image quality assessment to automatically select the optimal target histogram. Improvements in contrast and preservation of visual quality are taken into account in the target histogram, so this method avoids the problem of excessive increase in contrast. In the proposed method, the optimal target histogram is the weighted sum of the original histogram, homogeneous histogram and Gaussian histogram. Structural and statistical metrics of “naturalness of the image” are used to determine the weights of the corresponding histograms. Contrast images are obtained by matching the optimal target histogram. Experiments show that the proposed method gives better results compared to other existing algorithms for increasing contrast based on the transformation of histograms.
Detection of Stego Images with Adaptively Embedded Data by Component Analysis Methods
Authors:   Igor Sikorsky Kyiv Polytechnic Institute, Progonov Dmytro
Published: January 2022

Ensuring the effective protection of personal and corporate sensitive data is topical task today. The special interest is taken at sensitive data leakage prevention during files transmission in communication systems. In most cases, these leakages are conducted by usage of advance adaptive steganographic methods. These methods are aimed at minimizing distortions of cover files, such as digital images, during data hiding that negatively impact on detection accuracy of formed stego images. For overcoming this shortcoming, it was proposed to pre-process (calibrate) analyzed images for increasing stego- to-cover ratio. The modern paradigm of image calibration is based on usage of enormous set of high-pass filters. However, selection of filter(s) that maximizes the probability of stego images detection is non-trivial task, especially in case of limited a prior knowledge about embedding methods. For solving this task, we proposed to use component analysis methods for image calibration, namely principal components analysis. Results of comparative analysis of novel maxSRMd2 cover rich model and proposed solution showed that principal component analysis allows increasing detection accuracy up to 1.5% even in the most difficult cases (low cover image payload and absence of cover- stego images pairs in training set).

Published: January 2022

The quarantine restrictions introduced during COVID-19 are necessary to minimize the spread of coronavirus disease. These measures include a fixed number of people in the room, social distance, wearing protective equipment. These restrictions are achieved by the work of technological control workers and the police. However, people are not ideal creatures, quite often the human factor makes its adjustments. That is why in this work we have developed software for determining the protective elements on the face in real time using the Python scripting language, the open software libraries OpenCV v4.5.4, TensorFlow v2.6.0, Keras v2.6.0 and MobileNetV2 using the camera. The training program uses a prepared set of photos from KAGGLE — with a mask and without a mask. This set has been expanded by the authors to include different types of masks and their location. Using TensorFlow, Keras, MobileNetV2, a model is created to study the neural network by analyzing images. The generated neural network uses a model to determine the masks. You can preview the learning result of the network — it is presented as a graphic file. A program that uses the connected camera is then launched and the user can test the operation. This model can be easily deployed on embedded systems such as Raspberry Pi, Google Coral, and become a hardware and software automated system that can be used in crowded places — airports, shopping malls, stadiums, government agencies and more.

Published: January 2022

Background: Valid and reliable instruments are required to measure the level of information on contraceptive methods in adolescents to promote their correct use. Objective: To construct and validate a test of knowledge of contraceptive methods for adolescents between 15 and 19 years old. Method: A 36-item test was developed that included the different contraceptive methods and information on the characteristics, use, efficacy, advantages and disadvantages of these methods. Once validated by expert judges, a college in Ecatepec was randomly selected as data collection site. Students of the three school grades answered the test. Results: The test was applied to a total of 229 students between 15 and 19 years old (M = 16.22; SD = .978). The majority were women (66%), single (88.5%) and lived with their parents (62.9%). Of the 36 initial items, 31 showed discriminatory power between those who performed well on the test and those who did not. The difficulty index of the questionnaire was .45 and revealed a reliability index value of .739. Around 60% of the participants obtained a percentage below 50% of correct answers in the entire test. Only about 4% of participants got a percentage of correct responses higher than 70%. The categories of characteristics and use were those in which the participants performed best when answering 48% of these questions correctly. The worst was effectiveness, advantages and disadvantages with 33%. Conclusion: The test’s psychometric properties showed that it is a valid and reliable test for its application in Mexican adolescents. The results indicate that most adolescents of the simple do not have complete information about contraceptive methods and that they know the least about their effectiveness and side effects.

Authors: Arias Gallegos Walter L , Rivera Renzo
Published: January 2022

Background: The sexual behavior of women is associated with various protective or risk factors, which are important to assess. To determine the socioeconomic factors associated with the sexual behavior of Peruvian women within 15 and 25 years old. Method: A secondary analysis of the 2016 Demographic and Family Health Survey (ENDES) was conducted. Our sample was 7962 women from 15 to 25 years old, from all over the Peruvian territory. Associative analyzes were carried out on the age of sexual initiation, the number of sexual partners and the use of contraceptives, based on sociodemographic variables. Poisson regression with robust variance was also used. Results: It was found the factors, that are associated with the age of sexual initiation and the number of sexual partners, are the area of origin, marital status, educational level, employment status and socioeconomic level. While women who work and whose partners do not drink alcohol are the most likely to use contraceptives. Conclusions: It can be concluded that certain socioeconomic and work conditions act as protective factors of female sexual behavior, while having a partner who drinks alcohol is a risk factor.

Authors: Bulunuz Mızrap , Bulunuz Nermin
Published: January 2022

The purpose of this study was to reveal the leadership qualities of school principals in solving a noise problem at school. A single case study was selected as the research design. The study group consisted of primary and secondary school principals, one female and three males, working in the schools where the project was conducted. The main data collection tool of the study was interviews with the school principals. In addition, the study was supported with researcher observations and documents. The data were analyzed with inductive thematic analysis. The data were analyzed with a descriptive, explanatory and interpretive perspective in the context of noise prevention at schools. Four main themes emerged from the interviews with principals regarding noise at schools: "the noise problem," "administrative leadership," ”educational leadership," and "solution suggestions," The results show that participating in a project to prevent noise at schools has increased principals' awareness of noise and improved their leadership qualities in solving the noise problem. Principals are of the opinion that their schools are quieter than before and that the average academic success of their schools has increased. As a result, it has been determined that acoustic improvement, noise awareness training, rule making, discipline, value creation and culture formation are needed to create a quiet learning environment at schools.
Visual error correction of continuous aerobics action images based on graph difference function
Authors: Yin Dali , Shorman Samer M.
Published: January 2022

In order to solve the problem of the easy appearance of blurring images (easy to appear blur) or jagged effect after correction by traditional method, and as the visual error correction effect is not good, we propose a new visual error correction method of continuous calisthenics action image and a new algorithm for visual error correction. The continuous calisthenics action image is encoded and decoded, the error between the original image and the error image is obtained and with that the difference function is processed. Then the error compensation results are obtained and the visual error correction of the continuous calisthenics action image is realised. At the same time, a new algorithm for checking and correcting visual parallax matching errors is proposed in this paper. This algorithm can not only identify all matching errors in the parallax data, but also detect and correct them according to the continuity of shape representation, and effectively calculate the various performances of such matching algorithms automatically and quantitatively. The results show that the image processed by the proposed method has no significant visual error, and the peak signal-to-noise ratio and structural similarity are very high. The experimental results of the new algorithm also prove that the algorithm is very useful for the study of visual matching. It can be seen that the proposed method is effective and can be effectively used.

Published: January 2022

In order to discuss the application and mode of the forced modulation function in a sensor, the optical fibre emphasis function was established by referring to the geometric method, the tilt factor and the shape factor of the reflecting surface. These were introduced for the first time, and the corresponding mathematical model was established. The method of numerical simulation is systematically studied and multimode optical fibre parameters (including optical fibre of axial spacing, optical fibre core diameter and numerical aperture) are adopted. The reflective surface inclination and shape factors on the RIM–FOS intensity modulation characteristics are studied according to the obtained light quasi-Gaussian distribution model, establishing a general three-intensity modulation function of fibre optic sensor. The results show that the intensity modulation characteristic of specular reflection is obviously better than that of the diffuse reflection surface, and the peak value of the modulation function is five times that of diffuse reflection. The intensity modulation characteristic decreases with increase in the roughness of the reflection surface. The system can not only complete the RIM–FOS characteristic simulation and characteristic testing functions, but can also start-up the test and not be affected by the ambient light interference and power fluctuation of the light source. The test stability is good with high repeatability.

Authors: Wan Pengfei , Hamad Arbad Ahmed Mohamed
Published: January 2022

The paper establishes a related differential equation model about changes in financial interest rates. It uses information related to liquidity to feedback the law and stability of differential equations in interest rate changes. The article applies stochastic processes and partial differential equations to complex financial networks to confirm node yields in financial market networks. It confirms the existence of interest rate stickiness in Chinese financial markets. The advantage of this interest rate model is that when the external economic environment changes, the state of interest rates will also change accordingly.

Aspergillus flavus contamination of agriculture in Indonesia can cause problems to animal health and productivity. Some factors can support the appearance of contamination in feed, especially temperature and humidity. The main objective of this research was to investigate potency of Rhizopus spp. on inhibit A. flavus FNCC6109 in broiler chicken concentrate feed. The experiments were conducted dual culture method and the inhibition test of the Rhizopus spp. filtrate culture was incubated for 3, 4 and 5 days on in vitro. The in vivo test was directly applied in broiler chicken concentrate feed which added Rhizopus spp. filtrate culture concentration at 10% (v/v), 20% (v/v), 30% (v/v), 40% (v/v), dan 50% (v/v). The results showed that the Rhizopus spp. filtrate culture significantly (P?0,05) to inhibit the growth of A. flavus FNCC6109 both in vitro and in vivo. The percentage inhibition of Rhizopus spp. filtrate culture incubated for 5 days showed 67,47±2,10% relatively better results than 3 and 4 days, and therefore was used in the in vivo. Application of 50% (v/v) Rhizopus spp. filtrate culture to the broiler chicken concentrate feed significantly reduced 82% population of A. flavus FNCC6109 after 15 days incubated relative to that of negative control (concentrate feed without addition Rhizopus spp. filtrate culture and A. flavus FNCC6109).

Pengendalian populasi nyamuk Ae. Aegypti di Indonesia dilakukan sebagai upaya untuk menekan penularan virus dengue, salah satunya dengan penaburan larvasida temephos. Dosis operasional penggunaan temephos di Indonesia (1 mg/L) lebih tinggi dibandingkan dosis yang disarankan World Health Organization (WHO) (0,012 mg/L). Di Jawa Timur, terdapat temephos yang beredar komersial dengan perbedaan pada dosis penggunaan, yaitu10 gram/100 L air (10 G) dan 8 gram/100 L air (8G). Penelitian ini dilakukan untuk memeriksa kerentanan populasi larva Ae. aegypti yang berasal dari Jember (JEM), Surabaya (SBY), dan koleksi Laboratorium Entomologi Universitas Airlangga (LAB) terhadap temephos10G dan 8G pada dosis pemakaian tinggi (1 mg/L) hingga rendah (0,015625 mg/L). Uji mortalitas pada larva dilakukan sesuai dengan ketentuan WHO dengan replikasi 4 kali. Data dianalisis secara statistik. Hasil menunjukkan bahwa ketiga kelompoklarva Ae. aegypti mengalami >90% mortalitas dengan penambahan temephos pada dosis rendah (0,015625 mg/L) pada ambang waktu 240 menit, baik untuk temephos10 G maupun 8 G. Perbedaan respon mortalitas yang signifikan antara dosis tertinggi (1 mg/L) dan dosisterendah (0,015625 mg/L) ditemukan pada kelompok JEM pada dosis 8 G dan 10 G serta LAB pada dosis 8 G. Kelompok JEM dan SBY memiliki rasio resistensi 95 (RR95) temephos dengan kategori rendah (<5) dibandingkan dengan kelompok LAB. Semua kelompok masih memiliki kerentanan pada temephoskomersial pada dosis rendah (0,015625 mg/L). Dari hasil penelitian ini, kami menyarankan untuk menurunkan dosis operasional larvasida temephos yang digunakan untuk pengendalian populasi larva Ae. aegypti di Jawa Timur.
