Using of SIFT algorithm in the image of teeth model  can detect the features of the teeth image effectively. 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.

The effects of polymer network formed under UV irradiation with electric field application ( 50V  5Hz) to ferroelectric liquid crystal (FLC) molecules orientation and electrooptic characteristics have been studied. The polymer network formed in SmC*phase is anisotropic and fibrils-like  and a typical striped texture was observed in the cell. The FLC gels exhibit a symmetric V-shaped electrooptic characteristics with thresholdless voltage and high contrast ratio (40:1). A theory explanation of the unique properties is given by establishing a molecular orientation model and conducting a computer simulation. A good fitting of the electrooptic dynamic response of FLC gels has been obtained by introducing a potential (bulk anchoring energy) originated from the photo-cured polymer network. 2002 Taylor Francis.
