1. A video noise analyzer for detecting residual point noise in a video, comprising: an input for receiving a video to be analyzed; a temporal invariance detector structured to perform a differencing function between pixels of a same block of two adjacent frames and to generate a first pixel candidate list including pixels that have a relatively low rate of change between frames; a spatial outlier detector structured to generate a second pixel candidate list including pixels that have a relatively high level of intensity deviation from adjacent pixels; a combiner to combine the first pixel candidate list and the second pixel candidate list to generate a candidate noise pixel list; and a data store structured to contain data describing one or more pixels on the candidate noise pixel list or the blocks from which the pixels on the candidate noise pixel list were selected.
