A method for pixel extraction and replacement is disclosed. In one implementation, the method includes generating a set of pixel values and pixel value frequencies for a pixel presented in a series of digital images of a scene. A digital image of the scene which includes a pixel value for the pixel is received and a comparison is made between the pixel value and the set of pixel values. A determination is performed to decide upon substitution of the pixel value with a different pixel value based on the comparison. Other techniques are also disclosed.
