Abstract

Detection and subsequent removal of focus blur in digital images is often undertaken using expensive computational solutions. An alternative approach using simple gradient-based edge detection masks of varying sizes applied locally is presented here. Results indicate that this approach is able to provide significant improvement in the perceived sharpness of blurred edges.
