Особливості пошуку руху в відеозображеннях з малим відношенням сигнал-шум

Abstract

In this paper we analyzed some reasons of “false” motion vectors estimation in the process of inter frame video coding in video monitoring devices. It is shown that the using of criterion function considered a motion vectors bitrate allows to prevent from motion vectors occurrence in case of no motion. This allows to decrease of bitrate in video monitoring systems depending on compression ratio. It is also shown that the hierarchical motion vector estimation algorithm is perform well in case of small SNR. Difference of motion vectors found hierarchical method and exhaustive search does not exceed 6%.
