Abstract
The fusion for multi-focus images is a technique to generate a fused image. It requires finding an accurate alpha matte to generate a clear fused image. To generate such alpha matte we combine morphological filtering, median filtering and skeletonization to process each image and then we are able to determine its focus map. By using a compressive sampling technique with these focus maps we are able to determine an accurate alpha map. The fused images by the proposed method for several test images show satisfactory results compared to some conventional methods.
