Abstract: per describes an algorithm which, starting from the video signal, permits the user to recover the fertile information and to remove the false information introduced by the movements or vibrations of the source video sensor. Provided that some hypotheses on the exposure time and on the vibration spectrum are satisfied, a video sensor subjected to vibrations sees a static, or slowly moving, scene as a succession of frames which are identical, except for the fact that each one shows a shift with respect to the previous one. The electronic stabilization process finds the shift between the current frame and the previous one and recognizes the part due to the vibration from the target or the senor as valid movements. A stable output image can thus be obtained by shifting the output picture of the same evaluated amounts in the opposite direction. The electronic stabilization process finds application both for TV cameras and IR sensors. !4
