The purpose of multi-focus image fusion is gathering the essential information and focused parts from input images into a single image. These multi-focused are captured with different depths focus cameras. Multi-focus very time-saving appropriate in discrete cosine transform (DCT) domain, especially when JPEG used visual sensor networks (VSN). previous works DCT domain have some errors selection suitable divided blocks according to their criterion for measurement block contrast. In this paper, we variance Laplacian (VOL) energy (EOL) as measure contrast Also EOL VOL calculations directly prepared using vector processing. We developed four matrices which calculate easily domain. Our greatly reduce error due unsuitable selection. results proposed algorithms compared order demonstrate superiority output quality methods. several experiments fused by our methods other criteria.
