Description: The image feature extraction image matching and 3D information extraction based on image analysis and image processing alone one of the most important task in the fields of technology. Effective feature extraction algorithm is the key to image analysis and processing. Starting from the definition of point features, described the two common points feature extraction operator--- MMoravec operator and son Forstner operator theory, using the Moravec operator and Forstner operator can achieve the image point feature extraction, and from the extraction point The accuracy of features, the extraction speed of the two operators, and finally arrive at useful conclusions.
