Several recent high profile incidents involving law enforcement officers have resulted in the death of a citizen. In some of these cases, the use of deadly force by police was ruled as justified only to learn later that one or more officers were not truthful about what occurred. These incidents have called into question law enforcement's legitimacy and created a demand for greater transparency by equipping officers with body-worn cameras. Body cameras can act as independent, reliable witnesses with no bias or agenda. Federal, state, and local governments have pledged millions of taxpayer dollars to implement body-worn camera programs in police departments across the world, but research has revealed mixed results on the effectiveness of body-worn cameras. Effectiveness can be defined as a reduction in use of force incidents, citizen complaints, and offender and officer injuries during apprehension situations. Data were obtained from a large police department in the Southeastern United States that began using body-worn cameras in January 2015. A purposeful sample of 3 years of data before body cameras were introduced and 3 years of data after body cameras were introduced was analyzed using an interrupted time-series design. There was a statistically significant increase in use of force incidents and offender injuries during apprehension situations. There was no statistically significant change in citizen complaints or officer injuries. This research can assist police executives and program evaluators with providing expectations and setting goals for body camera programs.

Law enforcement requires comprehensive hiring and training practices in order to curb misconduct and turnover. Some of the available data suggests a shift in the dynamics of law enforcement toward a more objective approach that favors education, cognitive ability testing, a community policing orientation, and technological advances, such as body cameras, that hold enforcers of the law and the American public, accountable for misconduct and violations of the law. The utilization of various technological advances requires assessment and dynamic, comprehensive analysis. The present study examined the influence of education and the professionalization of policing hiring requirements, cognitive ability tests and training, community policing initiatives and training, and the utilization of body cameras, on the number of dismissals and voluntary resignations and police use of force incidents recorded, while considering gender composition, and ratio of officers to size of the community served, in a federally-released report. Many of the hypotheses were not confirmed. However, support for the relationship between education and officer dismissal, SARA training and all dependent variables, and gender composition and reduction in the number of use of force incidents reported, were substantiated. Implications, limitations, and directions for future research are explored herein.

Existing systems of scene reconstruction and theorethical basics necessary for scene reconstruction from images data are described in this work. System of scene reconstruction from video was designed and implemented. Its results were analyzed and possible future work was proposed. OpenCV, ArtToolKit and SIFT libraries which were used in this project are also described.
