In this approach  first  search over all scales and image locations by using a difference-of-Gaussian function to identify potential interest points that are invariant to scale and orientation. Second  select keypoints based on measures of their stability and a detailed model is fit to determine location and scale at each candidate location. Third  assign one or more orientations to each keypoint location based on local image gradient directions. Last  measure the local image gradients at the selected scale in the region around each keypoint. And then use the KNN algorithm to match the features. Through lots of experiments and comparing with other feature extraction methods  this method can detect the features of the teeth model effectively  and offer some available parameters for 3D reconstruction of the teeth model. the authors.   Inner and Outer Eye Corners Detection for Facial Features Extraction Based on CTGF Algorithm 会议论文 International Conference on Information Technology for Manufacturing Systems (ITMS 2011), Shanghai, PEOPLES R CHINA 作者:  Ran Zhou;  Qing He;  Jie Wu;  Chao Hu;  Max Q.-H.
