ABSTRACT
This chapter considers some video forensics-related scenarios and describes existing technologies needed by experts in the field of video forensics. In video forensics, mining for criminal evidence in videos recorded by a heterogeneous collection of surveillance camcorders is a major challenge. This is a new interdisciplinary field, and people working in the field need video processing skills as well as an in-depth knowledge of forensic science; hence, the barrier for entering the field is high. Rotation-, translation-, and scaling-invariant object recognition is a very important technique in video forensics. In video forensics, retrieval technique can be used to restore moving object in the foreground if some consecutive frames that contain the moving object are missing or damaged. To deal with video forensics-related problems, forensic experts need to develop more useful software tools to facilitate forensics-related investigations. In video forensics research, automating the video search process with the assistance of computers is a key objective.
