DETERMINING OUTLIER PIXELS OF SUCCESSIVE FRAMES

Circuits, systems, and methods for processing outlier pixels include a spatial filter and a temporal filter. The spatial filter is configured to compute a pixel difference for each pixel as a function of a pixel value of the pixel and pixel values of nearby pixels within each frame. The spatial filter is configured to dynamically add the pixel to a candidate list when the pixel difference exceeds a threshold value. The temporal filter dynamically removes a pixel from the candidate list when there is a divergence of a pixel value of the pixel in successive frames. The temporal filter determines a pixel in the candidate list is an outlier pixel when there is no such divergence in the successive frames.
