实现图像的清晰分割，效果明显,基于图像灰度-梯度构造的二维直方图，在此基础上计算目标与背景的二维Renyi熵-It can handle more types of images and get more accurate shape of the image edgee that pixels gradient information in combination with parameter of Renyi entropy which is adjustable

本程序采用C++语言计算图像LENA的一维图像熵和二维图像熵，并在控制台窗口中显示图像灰度值的一维和二维分布。-The program uses an image LENA C++ language computing one-dimensional and two-dimensional image entropy image entropy and displays images one-dimensional and two-dimensional distribution of gray

基于Matlab的一维图像熵和二维图像熵的计算。-Based on Matlab is one dimensional image entropy and two-dimensional image entropy calculation
