Abstract
Techniques are provided to detect and/or replace anomalous pixels. In one example, a method includes receiving an image frame comprising a plurality of pixels having associated pixel values. The method also includes selecting a kernel of the pixels comprising a center pixel and a plurality of neighbor pixels. The method also includes, if the center pixel value exhibits an anomalous pixel condition, calculating a replacement pixel value using a gradient associated with at least a subset of pixel values of the neighbor pixels. Additional methods and systems are also provided.
