Image Edge Detection Algorithm Based on Improved Canny Operator

Abstract

Referring to the image which is in the medical field,and similar to the medical image as red blood cells needs to detect cell size,roundness,and number of other features detection requirements,this paper proposes an image edge detection algorithm based on improved Canny operator.It calculates the optimal high and low dual-threshold through iteration arithmetic,and uses mathematical morphology to detect image thinning.Experimental results prove that this algorithm can effectively reduce interference and noise edge,and make more prominent detection characteristics of medical cell image.
