Claim 0:
1. A method of removing, by an imaging processing device, remanence artifacts from an image (fn) of a sequence of images captured by an infrared imaging device, the method comprising:
generating a remanence measure (ω*n,x) for at least some pixels in the image (fn) based on a difference between the pixels values of the image (fn) and the pixel values a previous image (fn−1) of the sequence; and
removing remanence artifacts from at least some pixels of the image (fn) based on a remanence estimation (μω,n,x) for each of the at least some pixels, each remanence estimation being generated based on the remanence measure (ω*n,x) and on one or more previous remanence estimations of the at least some pixels and on a model (W) of the exponential decay of the remanence.
