Abstract
A method and system are provided for discriminating areas of content from areas of noise in difference images of a digital video sequence. This allows the fewest bits possible to be used to encode areas of noise according to a video compression algorithm. The method comprises computing a difference frame from current image data and a reference frame; comparing at least one component of a candidate block within the difference frame to a threshold value to discriminate between content and noise; and encoding the candidate block if content is detected.
