shannon Tsallis escort Tsallis renyi entropy and their relative entropy

The functions include extensive Shannon and nonextensive Tsallis,escort Tsallis,and renyi entropy. the funcition names start with K_q_ indicate relative entropys Usage for all the seven functions:

基于熵的图像分割方法有很多，Tsallis灰度熵是其中的一种，它与其他传统熵相比，考虑了图像中目标和背景类内灰度级的均匀性-There are many entropy-based image segmentation method, Tsallis grayscale entropy is one of them。 Compared with other traditional methods, it considering the target image and the backgroun

Renyi熵阈值的方法与Tsallis熵相类似，但是计算跟简单，这个是一篇文献的仿真，有实验结果。-Renyi entropy threshold method with the Tsallis entropy is similar, but the calculation is more simple, this is a literature of simulation and experimental results.
