Wavelet-Based Extraction of three-dimensional model of thesis, including the reply code and ppt.1. Three-dimensional model of the implementation and standardization of the express pre-treatment process, on this basis, developed a visual search experiment of feature extraction experiment platform. 2. Combination of spherical harmonic transform to obtain rotation invariant feature vector with reduced dimension of the characteristics of ray-casting based on the implementation of feature extraction methods, the evaluation by searching the parameters of the experiment to determine the best value. 3. Analysis of the basic ray casting method and the ray casting method to improve the shortcomings, a wavelet transform based on the three-dimensional characterization of the Ways. Ray-casting algorithm for the expansion of the sampling points Chebyshev sequences discrete wavelet transform, then the use of spherical harmonic transform to obtain rotation invariant feature vector. 4. Wavelet tr
