A Novel Defocus-blur Region Detection Approach Based on DCT Feature and PCNN Structure

The motion or out-of-focus effect in digital images is the main reason for the blurred regions in defocused-blurred images. It may adversely affect various image features such as texture, pixel, and region. Therefore, it is important to detect in-focused objects in defocused-blurred images after the...
