This is known as VCcomplex . The VCcomplex is a combination of the input image and the vertical direction that is added to the vertical direction of the input image and the detected edge information. When the combination of the larger quantity of images is created we process the ADD operation. In the same way when there is a decomposition of the smaller quantity of images we process the difference operation. Accordingly we emphasized the edge information by using the ADD and difference operation for the combination and decomposition. First we calculated the ADD operation to the same direction of the input image and the calculated edge information. The VCcomplex was a combination of the larger quantity of images which was in the horizontal direction and this was added to the horizontal direction of the input image and the calculated edge information. When there is a combination of the larger quantity of images we use the ADD operation.

The VCcomplex is a combination of the horizontal and diagonal direction that was added to the horizontal and diagonal direction of the input image and the detected edge information. In the same way as equation 12 when it is a decomposition of the smaller quantity of images we process the
