One kind of macrophages images edge detection method

Edge detection plays a fundamental role in higher level processing. Aiming at the actual macrophages images characteristic, this paper presents the method of image edge detection based on mathematical morphology. The image is first converted color space from RGB to YIQ. Then the image is segmented by Otsu threshold algorithm. And then the opening and closing of morphological filter are used to process the image. Finally, the edge detection operator based on morphology is carried out to extract the boundary of macrophages image. Experimental results show this method works successfully in the edge detection of macrophages microscopic images.
