Any image processing technique, such as enhancement, edge detection, smoothing etc should incorporate the respense function of human. Edge detection a high-pass filter sharpens an image this program analyzes every pixel in an image in relation to the neighboring pixels to sharpen the image. Several standard digital image enhancement techniques have been applied frequency enhancements for improved edge detection and visualization. Abstract edge detection is a process that detects the presence and location of edges constituted by sharp changes in intensity of an image edges define the .
