说明：  建武和申铉京等人充分利用图像空间邻域信息，引入均值-中值-梯度共生矩阵模型，并结合Renyi熵相关理论, 提出一种结合纹理信息的三维Renyi熵阈值分割算法. 同时给出了该方法的快速递推公式。
(Jianwu and Shin Hyun Beijing, who make full use of the image spatial information, the introduction of the mean- in value- gradient co-occurrence matrix models, combined with the Renyi entropy theory, put forward a combination of the three-dimensional texture information Renyi entropy threshold segmentation algorithm at the same time to fast recursive formula of the method.)
