Binary image Processing is the significant component part for detection of image edge.In this paper
different algorithms and operators for the edge detection are summed up and analyzed.Matlab and Visual C++ programming are used for realization of the image edge detection and basic processing.According to the results of a number of image edge detections with the algorithms and the results through the test examination
Canny operator is one kind of very good pragmatic means for edge detection
