The present invention facilitates efficient and effective detection of pixel alteration. In one embodiment a pixel alteration analysis system includes a difference summing multiple engine component and a control component. The difference summing multiple engine component determines the sum of differences between pixel values in a plurality of pixels. The control component determines an indication of motion based upon said relationship of said pixels in said plurality of pixels. In one exemplary implementation, the difference in values corresponds to a relationship between values of pixels in a block of pixels at different frames. The number and configuration of pixels in a block partition can be flexibly changed.
