Abstract :
Recently, High Efficiency Video Coding (HEVC or H.265) standard becomes to be widely applied and exploited. This compression standard can achieve very low video bitrates and allow deployment of mobile security cameras with wireless data transmission. The paper deals with subjective evaluation and assessment of the above mentioned standard and its impact on reliability and efficiency of person identification under very low video bitrate condition. The evaluation procedure is based upon modified test with reference when the separate reference database of persons appearing the testing video sequences is available. The reference database is a set of standard portrait photos. Results of the paper show applicability of HEVC compression standard in the security CCTV camera systems especially in comparison with earlier widely used standards as H.264.
