Abstract
The present invention apparatus and method uses a recursive filter to estimate the instantaneous intensity and temporal rate of change in intensity for object points in consecutive images of an image-sequence. The estimates of the intensity and its temporal rate of change are updated for each new image in the image sequence. The amount of smoothing introduced by the recursive filter is dependant upon the estimates computed for the intensity and temporal rate of change. As such, the recursive filter corrects the image sequence in accordance with each new set of estimates. Since motion in an image-sequence is implicit in the rate of change of intensity, the recursive filter is able to achieve motion compensated enhancements.
