1. A method of detecting dead pixels of image frames, the method comprising: receiving, at a computing device, a sequence of image frames; aligning, from the sequence of image frames, pairs of image frames; for a given pair of image frames, determining differences in intensity of corresponding pixels between the aligned pair of image frames; based on the differences in intensity of corresponding pixels between the aligned pair of image frames, determining moving objects in the pairs of image frames; determining common pixel locations indicative of areas in the pairs of image frames having moving objects over a portion of the sequence of image frames; and based on a number of the common pixel locations for a given pixel location being above a threshold, identifying the given pixel location as a dead pixel.
