Claim 7:
8. An imaging processing device comprising:
at least one memory storing an image (fn) of a sequence of images captured by an infrared imaging device and one or more remanence measures (ω*n,x) of at least one previous image in the sequence; and
one or more processors configured to remove remanence artifacts from the image (fn) by:
generating a remanence estimation (μω,n,x) for at least some pixels in the image (fn) based on a difference between the pixel 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 an estimation of the remanence generated based on the remanence estimation (μω,n,x) and on one or more previous estimations of the remanence of the at least some pixels and on a model (W) of the exponential decay of the remanence.
