Abstract

The image processing plays a significant role in many applications such as medical and defense applications. Consequently, there is more demand for the research in computer vision and image processing field. Canny Edge detection algorithm is the standard for many years. But still there are some limitations like more computation time and the area utilization. As the existing algorithm requires the storage for the overlapping block generated from the non-overlapping block, the area utilization is more and also accessing delay increases. Design of block level edge detector using spatial mask filter is proposed to overcome these effects. In this proposed design the edge detection is applied at the block level. The creation of overlapping block from the non- overlapping is performed with help of shifting operation. Thus the area and delay can be reduced by performing the shifting operation which generates the overlapping blocks from the non-overlapping block without any storage requirement.
