Study of Image Edge Detection Techniques
Edges characterize boundaries.Edge detection is a problem of fundamental importance in image processing.The key of edge detection for image is to detect more edge details,reduce the noise impact to the largest degree.In this paper the comparative analysis of various image edge detection techniques is presented.In order to evaluate these techniques,they are used to detect the edge of chromosome image.Firstly,the iterative thresholding algorithm and morphologic erode algorithm together are applied to enhance both the edges of the chromosomes and the contrast of the image.Then,Sobel operator technique,Roberts technique,Prewitt technique and Canny technique are used respectively to detect the edges of the chromosomes in the image.
