Abstract

Described herein are systems and methods for on-the-fly detection of a defective pixel in an image that may include: receiving the image; for each analyzed pixel in the image, selecting an analyzed cell, wherein the analyzed cell includes a plurality of pixels; performing statistical distribution analysis for the plurality of pixels in the analyzed cell; determining an allowed statistical distance for the analyzed pixel relative to the analyzed cell; and determining that the analyzed pixel is a defective pixel if a computed statistical distance of the analyzed pixel exceeds the allowed statistical distance.
