Abstract :
Motion estimation and compensation is the most computationally complex module of video coder. In this paper, an innovative algorithm is proposed for a further complexity reduction of the motion estimation (ME) module of video coder by employing motion detection prior to motion compensation. A dynamic motion detection (DMD) module can be added to the video coder in order to decide whether the current block contains motion or is with zero motion. This work propounds a DMD module which depends on motion activity. Generally, the variance of the difference of two consecutive frames is a good criterion to measure motion activity. We have applied the dynamic calculation of local variance of the difference frame as a threshold to detect the motion activity. The result shows that this proposed scheme can simplify the encoder complexity, maintaining high compression rate and good video quality. Moreover this method is valid for every kind of video sequences having a static and moving background.
