Abstract :
Given a sequence of blurred low resolution images, the aim of this work is to produce a sequence of higher resolution and restored images. It is assumed that the point spread function of the given imaging process is a combination of a known blurring function and an estimated local motion function. The local motion estimation is obtained by the respective group delays of local adaptive filters. Preliminary experimental results are presented
