Cold pixels are produced by individual sensors in the CCD or CMOS camera with lower than normal sensitivity (even as low as zero, a 'dead' pixel). They appear as abnormally dark pixels in otherwise bright areas of an image. Cold pixels may appear at the same position in every z-slice of a 3D stack, in every time frame, and in multiple channels.
Huygens Essential and Professional have a Hot & Cold Pixel Remover, which is a tool that can automatically detect, visualise, and correct cold pixels.
