Toward Relighting and View Synthesis for Human Portraits

Author(s): Sun, Tiancheng | Advisor(s): Ramamoorthi, Ravi | Abstract: Human portraits are ubiquitous in our everyday life. However, after we take the portraits using the camera, the lighting condition of the captured image cannot be easily changed. Previous works have investigated how to change the lighting condition of a portrait, but they usually require special hardware to achieve relighting. In this thesis, we study the problem of portrait relighting, aiming at accuracy and practicality. We present several novel approaches that enable relighting portraits after the capture.With the goal of practical relighting that can be used in everyday life, we first develop single image portrait relighting. We leverage the prior of human portraits, and train a neural network that learns to perform relighting given only a single portrait. Our network can achieve convincing relighting results with very limited computation power, enabling real-time portrait relighting applications. Next, we focus on how to achieve precise relighting under point lights. We capture the portrait using discrete point lights under a light stage, and super-sample the location of the point lights to achieve high-frequency relighting. This enables finer controls on the shadows on human faces. Finally, we investigate changing both the viewpoint and the lighting condition of captured portraits. To this end, we propose neural light-transport field (NeLF). Given only 5 frontal portraits, this neural rendering approach can generate portraits from novel views under arbitrary natural lightings.
A NOVEL MIXED STEGNOGRAPHY FOR PROVIDING SECURITY FOR THE DIGITAL DATA

Stegnography is the craftsmanship and study of composing concealed messages so that nobody, aside from the sender and mean beneficiary, associates the presence with the message, a type of security through lack of clarity. Stegnography is the plan of concealing the presence of mystery data by hiding it into another medium, for example, sound, and video or picture records. In Stegnography the shrouded document doesn't change the structure of the mystery message, however conceals it inside a spread picture with the goal that it can't be seen. This application allows you to insert or shroud significant or private messages or documents into wmv without influencing the nature of genuine information or records. It accomplishes this by utilizing the least critical pieces of these documents for inserting information which are not utilized by the Image watchers or Image editors. It permits you to install the messages or records in scrambled structure utilizing 32 piece DES calculation which implies that once encoded, the message or document could be recovered (or unscrambled) from a Master record simply subsequent to indicating the right secret phrase which was utilized at the hour of . On the off chance that you indicate encryption to be utilized, you'll need to determine a secret phrase which is at least 8 characters long.

Cyber-Attacks, Cryptocurrencies, and Cyber Security

This paper provides comprehensive evidence on the effects of cyber-attacks (cyber-crime, cyber espionage, cyber warfare and hacktivism) and cyber security on the risk-adjusted returns, realised volatilities and trading volumes of the three main cryptocurrencies (Bitcoin, Ethereum and Litecoin). We find that stronger cyber security is generally effective in increasing the risk-adjusted returns of cryptocurrencies and trading activity even in the presence of cyber-attacks. Hacktivism appears to be the most significant threat to cryptocurrency investors. Further, cyber-attackers hitting the cryptocurrency exchanges are most likely to attack other sectors (government, industry and finance) as well. In addition, in the case of the US they target the government and industry sectors in preference to the cryptocurrency exchanges given the corresponding potential benefits and costs. In all cases appropriate strategies should be designed to enhance cyber security.
Comparison of crossover operators in genetic algorithm for vehicle routing problems

Genetic algorithm (GA) is a popular metaheuristic with wide-ranging applications, e.g. in routing problems such as traveling salesman problem (TSP) or vehicle routing problem (VRP). Seeking the best combination of parameters in GA application is the key objective in the line of research involving GA. One possible factor to be tested is the operator used for crossover. For VRP, a number of research reporting good performance use the order crossover (OX) operator. For TSP, one paper proposed the modified cycle crossover (CX2) operator and reported that it is better than OX and the partially mapped crossover (PMX). The interest and objective of this paper is to test these three operators in a VRP setting. Excluding the crossover operator, other good principles of GA for VRP obtained from the literature are maintained. The experiment results suggest these findings. Firstly, CX2 is expensive in run time and has difficulty escaping from local optimum but leads to the best fitness value compared to the other operators. Secondly, PMX ranks second both in the fitness performance and run time. Thirdly, while OX has slightly inferior performance, it is able to explore wider search space and therefore still has lots of potential for future research.

Implementation and Analysis ModSecurity on Web-Based Application with OWASP Standards

The use of a web application firewall is a necessity to protect web-based applications from attacks. The application of a web application firewall on web-based applications can reduce attacks that occur. From the security aspect, it is necessary to know how effective a web application firewall is to protect and minimize malicious attacks that attacks web-based applications. This research uses the OWASP standard as a step to perform penetration testing. From the three experiments conducted, the web application firewall effectively protects vulnerable web applications by 66% and can protect two vulnerabilities with high-level risk. Vulnerability measures that can be taken as prevention efforts and security level assessments are based on Common Vulnerability and Exposures (CVE).
Vision-based pose estimation algorithm with four coplanar feature points via an incident-ray-based camera model

The pinhole imaging model assumes that all the projecting rays intersect at the effective pinhole point. The restriction of this camera model will result in low accuracy of vision-based pose estimation. Furthermore, the camera calibration gets the global optimal solution of intrinsic and extrinsic parameters, which will affect the calibration accuracy of intrinsic parameters and then pose estimation accuracy is also affected. In this paper we completed the pose estimation with four coplanar feature points via an incident-ray-based camera model. Two parallel planes are used to perform the ray-pixel mapping. The projecting ray could be defined by its two intersections with the two planes. In this way, the camera is parametrized by the image plane and the two parallel planes. Based on this camera model, through four coplanar feature points, the object pose could be estimated. The whole process consists of both a non-iterative step and iterative step. In the non-iterative step, the initial estimation of the pose is obtained and then it is refined in the iterative step. Experiment results on pose estimation by the proposed algorithm and the other existing algorithms demonstrate the superiority of our algorithm.

Analysis of Tiv clitics

Tiv language has both major and minor word-formation processes, and cliticization belongs to the minor process. This study debunks an erroneous assertion by researchers of Tiv extraction that Tiv morphology is devoid of clitics. The non-inclusion of cliticization as a word-formation in Tiv is long overdue. Though clitics are infinitesimally small in the Tiv grammar, their minuteness should not be ignored. This paper argues that the Tiv language has enclitic m, which is added after its hosts, usually verbs, it performs pronominal functions. This paper classifies Tiv clitics, discusses the formation of clitics in Tiv, and states the functions of Tiv clitics. The researcher made use of observation as a primary source of data elicitation, and documentary sources were equally used in the review. It has been discovered that researchers on the Tiv language have not given any attention to clitics in the language. It has been found out that nam (give me) and wuhem (my co-wife) were considered as objects in the previous studies. Researchers mistook clitics for affixes. Finally, the Tiv language only has enclitics.

Towards Combining Object Detection and Text Classification Models for Form Entity Recognition

Due to the increasing volume of forms that are generated in a daily basis, the automatic extraction of the information included in these template-based documents is greatly demanded. However, this is not a straightforward task due to the great diversity of templates with different location of form entities, and the quality of the scanned documents. In this work, we have made a first step towards form entity recognition by combining computer vision and natural language processing techniques. First, we have applied state-of-the-art deep object detection and semantic segmentation models for localising the position of form entities based only on visual features. Afterwards, we have studied different transfer learning approaches (fine-tuning and feature extraction) for classifying the text content of the localised form entities. The studied models require low computational and image resources, making them a feasible alternative to state-of-the-art models even if their performance is slightly worse.

Perception to Educational Games towards Learning Attitudes of College Students in St. Mary’s College of Bansalan Inc

Many lauded methods promise to provide a remedy to learning issues, and education is prospering. However, the most efficient manner of conveying knowledge and teaching skills is to approach learning through pleasure. And educational computer game research has exploded due to the widespread notion that games may provide a variety of learning benefits, as well as the fact that games extremely popular among younger generations. Games-based learning has piqued the interest of educationalists and businesspeople who want to take use of the qualities of computer games, which seen as a potentially effective method of teaching and learning by some. Despite this enthusiasm for game-based learning, there is a paucity of scientific evidence to back up the approach's validity in the larger context of education and gaming. Students are experienced to learn by doing with the usage of digital games, according to the report. Educational games provide a learning environment that caters to a wide range of learning methods. Have proven that by making digital games easy or pleasant to learn, students' negative attitudes can be transformed. Despite this, many educators opposed to incorporating digital gaming into the classroom. It was shown that adopting educational games as a learning method can help students learn more across a variety of learning domains, including cognitive, emotional, and psychomotor skills. Students also more motivated to study and learn.
