Image denoising searching similar blocks along edge directions
作者：
Highlights：
•
• We use the different approaches to handle the pixels in the edge region and those in the smooth region.
• For the edge pixels, we search for similar blocks along the edge directions instead of the fixed directions.
• An efficient approach to determine the search neighborhoods that are well to image details is introduced.
