扩频伪码捕获方法，截获搜索策略及截获判定。(Spreading pseudo-code acquisition method, the to intercept search strategy and intercepted judgment.)

In order to capture the spatial dependence of gray-level values which contribute to the perception of texture, a 2d dependence matrix known as a gray-level co-occurrence matrix is extensively used in texture analysis.So, this is a code that calculate a co-occurrence matrix of the image and return the following features: ENERGY, CONTRAST, CORRELATION and HOMOGENEITY.
