Facial Images

Being able to robustly reconstruct 3D faces from 2D images is a topic of pivotal importance for a variety of computer vision branches, such as face analysis and face recognition, whose applications are steadily growing. Unlike 2D facial images, 3D facial data are less affected by lighting conditions and pose. Recent advances in the computer vision field have enabled the use of convolutional neural networks (CNNs) for the production of 3D facial reconstructions from 2D facial images. This paper proposes a novel CNN-based method which targets 3D facial reconstruction from two facial images, one in front and one from the side, as are often available to law enforcement agencies (LEAs). The proposed CNN was trained on both synthetic and real facial data. We show that the proposed network was able to predict 3D faces in the MICC Florence dataset with greater accuracy than the current state-of-the-art. Moreover, a scheme for using the proposed network in cases where only one facial image is available is also presented. This is achieved by introducing an additional network whose task is to generate a rotated version of the original image, which in conjunction with the original facial image, make up the image pair used for reconstruction via the previous method.

The research objective is to study the current state of hand-to-hand combat and determine the prospects for its development. Materials and methods. The researchers studied the documents on organizing and holding the competitions that took place in 2014-2016, the number and quality of their participants, coaches, hand-to-hand combat referees. The researchers analyzed training programs and competition rules of the most popular combat sports, constituent documents of public associations engaged in hand-to-hand combat development, normative documents on physical training of law enforcement agencies, the Armed Forces of Ukraine and armies of the world’s leading countries. Results. Hand-to-hand combat is closely related to solving military tasks. Due to its ability to adapt to modern military requirements, it is included in military training programs of various law enforcement agencies, the Armed Forces of Ukraine and armies of many countries of the world. The sports type of hand-to-hand combat is the basis for shaping and improving professional and applied skills and has its peculiarities, namely combat (applied) sections included in its training program and competition rules. The analysis of regulatory documents of hand-to-hand combat competitions of different levels among adults held in Ukraine in 2014-2016 proved that the overwhelming majority of them, 65% (of the total number of competitions held among adults) are competitions among employees of various law enforcement agencies and servicepersons. The analysis of competition rules revealed the peculiarities of organizing and holding competitions in this sport, in particular the possibility to hold competitions demonstrating the techniques used in standard situations of a real combat with an enemy, with and without weapons. This provides an opportunity to control servicepersons’ and law enforcement officers’ proficiency level of the applied section. Conclusions. The modern hand-to-hand combat is a unique sport that combines sports and applied types. Due to its peculiarities, it is currently a significant part of combat and professional training of servicepersons and law enforcement officers.

3D face reconstruction from a single 2D image is a fundamental computer vision problem of extraordinary difficulty that dates back to the 1980s. Briefly, it is the task of recovering the three-dimensional geometry of a human face from a single RGB image. While the problem of automatically estimating the 3D structure of a generic scene from RGB images can be regarded as a general task, the particular morphology and non-rigid nature of human faces make it a challenging problem for which dedicated approaches are still currently studied. This chapter aims at providing an overview of the problem, its evolutions, the current state of the art, and future trends.

This article analyzes the relevant legislation, identifies the basic criteria for defining the concept of the civil service of other types in the Russian Federation, and describes the current state of its legal regulation. The service of other types is carried out in the federal-state bodies and organizations subordinate to them; such organizations perform special functions to ensure security, law and order, combat crime and protect citizens’ rights and freedoms. The author identifies the reasons for the abolition of such a concept as “law enforcement service” in the civil service systems and considers the process of its transformation into a new segment within this system. Based on the conducted comparative analysis of legislative and subordinate legal acts containing relevant regulatory provisions, the analysis shows that today the civil service of other types is carried out in state bodies defined as law enforcement agencies. To reflect the current state of legal regulation for the civil service of other types, the author notes an increase in the corresponding legislative framework in recent years. The issues of legal regulation of work in the field of civil service of other types are worked out in special laws regarding employees of customs authorities, internal affairs bodies, the federal fire service, the criminal justice system, and enforcement bodies. In addition, the article outlines the key priorities for further improvement of legal regulation.

The article analyzes the current state of legal support of quarantine requirements and sanitary rules and regulations for the prevention of infectious diseases in foreign countries and Ukraine. To achieve this goal, an analysis of the current legislation of some foreign countries and Ukraine on the grounds for establishing liability for violation of quarantine and sanitary norms and rules. It has been established that the COVID-19 pandemic has forced the governments of different states to introduce administrative and criminal liability in case of violation of quarantine and sanitary norms and rules. To ensure these measures, penalties for non-compliance with the quarantine regime have been introduced, with penalties ranging from warning to imprisonment and even the death penalty. It is established that in Ukraine the issues of administrative and criminal liability for violation of quarantine and sanitary rules and regulations for the prevention of infectious diseases are regulated by Articles 42, 44-3 of the Code of Administrative Offenses and Article 325 of the Criminal Code of Ukraine. It is determined that one of the problems of ineffective application of Articles 44-3, 42 3 of the Code of Administrative Offenses and Article 325 of the Criminal Code of Ukraine is an array of new rules for the prevention of COVID-19, which is constantly changing and introduced by various law enforcement agencies. The study found that despite the adoption of regulations that established liability for violations of statutory rules and regulations introduced by both foreign countries and Ukraine to prevent COVID-19, they have a number of legal conflicts, inconsistencies and gaps.

The Impact

Purpose The growth of police operated surveillance cameras has out-paced the ability of humans to monitor them effectively. Computer vision is a possible solution. An ongoing research project on the application of computer vision within a municipal police department is described. The paper aims to discuss these issues. Design/methodology/approach Following the demystification of computer vision technology, its potential for police agencies is developed within a focus on computer vision as a solution for two common surveillance camera tasks (live monitoring of multiple surveillance cameras and summarizing archived video files). Three unaddressed research questions (can specialized computer vision applications for law enforcement be developed at this time, how will computer vision be utilized within existing public safety camera monitoring rooms, and what are the system-wide impacts of a computer vision capability on local criminal justice systems) are considered. Findings Despite computer vision becoming accessible to law enforcement agencies the impact of computer vision has not been discussed or adequately researched. There is little knowledge of computer vision or its potential in the field. Originality/value This paper introduces and discusses computer vision from a law enforcement perspective and will be valuable to police personnel tasked with monitoring large camera networks and considering computer vision as a system upgrade.

In this paper, we propose a novel approach for 3D face reconstruction from multi-facial images. Given original pose-variant images, coarse 3D face templates are initialized to reconstruct a refined 3D face mesh in an iteration manner. Then, we warp original facial images to the 2D meshes projected from 3D using Sparse Mesh Affine Warp (SMAW). Finally, we weight the face patches in each view respectively and map the patch with higher weight to a canonical UV space. For facial images with arbitrary pose, their invisible regions are filled with the corresponding UV patches. Poisson editing is applied to blend different patches seamlessly. We evaluate the proposed method on LFW dataset in terms of texture refinement and face recognition. The results demonstrate competitive performance compared to state-of-the-art methods.
