BSTRACT
The image edge detection has become one of the most important parts of image processing with the development of computer technology. Image edge detection is the first step of image analysis, also the basis of image segmentation, feature extraction and image recognition. Edge detection traditionally image processing and analysis in the areas of focus of the study. Edge detection in computer vision and image analysis applications play an important role, is an image analysis and recognition of the important links. Edge detection of image analysis and pattern recognition is the main feature extraction methods, test results directly to determine the accuracy and results of follow-up treatment.
Designed primarily for edge detection methods and algorithms related research. 5 kinds of popular classical edge detector is theoretically analyzed, and VC + + programming through the five kinds of operators. And then combined with the experimental results on various operators have a comparative analysis, that the pros and cons of the various operators and the scope of application, as the actual application provides control and reference.
