Abstract

We describe a compact algorithm that can on the fly detect and correct isolated missing pixels in the output stream of an image sensor, without significantly degrading the image quality. The algorithm is in essence a small kernel non- linear filter. It is based on the prediction of the allowed range of gray values for a pixel, for the gray values of the neighborhood of that pixel. A few examples will illustrate the effect of the algorithm on realistic images.
