摘要：This paper presents a study on image pixels u sing block positioning pixel subtraction technique to analyse the changes that occur in that region of interest. The changes that happen in the pixels represent the motion translation. Processing a whole video sequence in order to view a certain area of interest will increase the computational and processing time. In order to avoid this situation, the block positioning pixel subtraction technique is applied. The block-based positioning subtraction technique extracts the small block of interest to be processed. This small block of interest is processed individually without the need to process a full frame. This technique divides the frames into small 8 . 8 macro blocks and identifies the pixels of an area of interest in the small block as motion. Identified motion with changes of pixels value is extracted from the small 8 × 8 macro- block to further analyse the motion changes.
