Abstract — In this concept describes a various techniques of edge detection by using image segmentation. The several techniques are Roberts Edge detection, Sobel Edge Detection, Prewitt Edge Detection, LOG Edge Detection, and Canny Edge Detection. This Paper mainly focused Sobel edge detection and Threshold edge detection techniques are implemented using MATLAB and result is obtained. We have taken different types of microscopic images in web site which affects human body by making diseases in virus and bacteria. Now we analyze this paper defines compare using Sobel Edge Detection and Threshold Edge Detection and demand assures which provides better performance on edge detection using microscopic image
