One of the frequently encountered problems in photography is the appearance of motion blurring effect due to either object movement or camera motion associated with the speed of the camera (shutter speed) when pictures are taken. This Paper presents a novel but simple method of detecting unwanted motion blur effects that appear local within an arbitrary area on a digital image. The proposed method uses various size block-based discrete cosine transform (DCT) calculations on the distorted image… CONTINUE READING
