Abstract :
A new technique is presented for combining restored images which have different characteristics. Related restorations can be combined at the pixel level by performing a weighted average operation where the weights are derived from local image gradients estimated by the Sobel edge detector. The resultant image contains the best visual characteristics of the original restorations.
