Two typical detection operator contrast

Edge detection is an important element of image analysis. The edge of the image is the most basic features of edge detection in image processing and computer vision occupies a special place, it is the underlying visual processing in one of the most important aspects. The detection operator is the commonly used method of the extraction of edge detection. Canny operator and the operator log as the most representative of the edge detector, this article compares the two operators of the advantages and disadvantages. Through experiments, carried out the analysis, compared with the final results of the experimental and theoretical analysis of the results.
