By analyzing influence of moving objects on nonuniformity correction algorithm based on image registration

a nonuniformity correction algorithm for infrared image with moving objects is proposed based on assume that radiance of moving objects

which are in adjoining two frames

is stable. Influence of moving objects can be eliminated through replacing the radiance of the objects in the last frame with that of the same location in current frame. Thus

the scene corrected frame can be calculated by nonuniformity correction algorithm based on image registration. Then

the final corrected frame can be obtained through correcting the radiance of the moving objects. The tests with synthetic and true infrared scene sequences indicate that the proposed algorithm can solve the problem of nonuniformity correction for infrared image with moving objects efficiently.
