gabor二维滤波器，能有效的提取细节纹理信息。-two-dimensional gabor filter, can effectively extract the details of texture information.

基于光线投射变换的三维模型特征提取,以三维模型的重心为球心的最小包围球剖分成一系列同心球壳，落入每个球壳的射线与模型表面的交点定义一个球坐标方程。一般地，对于每条射线，它与模型表面的多个交点同时落入一个球壳的几率大大降低了，这样就可以尽可能的减少信息的丢失。-Transform-based ray-casting feature extraction of three-dimensional model to three-dimensional model for the core focus of the post-mortem into the smallest ball surrounded by a series of concentric spherical shell, falling into the hands of each spherical shell model of the surface-ray intersection with the definition of a spherical coordinate equation. In general, for each ray, the surface of it with the model number of intersection points falling into the hands of a spherical shell at the same time greatly reduces the probability that such a reduction could be as much as possible the loss of information.

An alternative to Matlab s HIST, function HISTW prevents extreme values in top and bottom percentiles of an input vector affecting the histogram s scaling, obscuring location and shape of the distribution s main mass. Limits of x and y (maximum only) axes can be set, and a marker line drawn at given x position. In contrast to HIST, bin size can be explicitly specified, and relative, rather than absolute, frequencies are plotted.
