In video compression, the motion compensation phase passes through block matching step. During this phase we search in two successive frames about a block in the last one with respect to its original position in the first one and apply mathematical technique to decide if it matches or not. The proposed method is for matching phase, the normal methods are Mean Absolute Difference (MAD), Mean Square Difference (MSD), Pel Difference Classification (PDC) and Integral Projection (IP). We proposed a method based on the subsampling while applying IP then adding the adaptively phase across a preprocessed factor depending on the nature of the frame content.
