Abstract

A multi-scale optical flow motion estimation based algorithm is developed for algebraic nonuniformity correction. First, the algorithm use time domain low pass filter filtering the random image frames noise. Then, use multi-scale optical flow estimation of the next frame. With these scene estimates and record frame, we can carry out nonuniformity correction. The strength of the algorithm lies in its good noise immunity, simple calculation and ability of real time processing. The fundamental and the flow of the proposed technique are described and the performance is demonstrated with infrared camera developed.
