This paper presents the edge detection and level of pixels to proceed further. Edge Detection is a kind of image- segmentation process and image-segmentation is one of the pre-processing steps in Image Processing. It is used in many places such as the detection of an object lying on the line of sight, the extraction of damaged videos, enhancing the image so it can be recognized well by adjusting the light and dark areas etc. There are variety of image detection algorithms, for example, Canny Edge Detection, Prewitt Edge Detection, Sobel Edge Detection, Roberts Edge Detection, etc. but this research paper will focus on Canny Edge Detection algorithm as it overcomes the shortcomings of other very popular edge detection algorithm called as Sobel Edge Detection algorithm and how we can use the technique for precise detection of obstacles as it is a very important part for our robot system should include.
