计算图像直方图。给定图像，得到图像的直方图。(computing the histogram)

说明：  这个是matlab里基于LR算法对模拟运动模糊并且加入高斯噪声进行复原的算法(This is carried out in the recovery matlab LR algorithm based simulation of motion blur and add Gaussian noise algorithm)

可以通过边缘检测等等算法，实现霍夫圆变换(The edge detection algorithm and so on, realize the circle Hough transform)

说明：  在很多图像处理的过程中，需要判别一个图像的清晰度，和图像分割结果的优劣，于是就引出了信息熵的概念，绝大多数时候，它都被用来作为评价图像的一个量化标准。(In many image processing processes, it is necessary to distinguish the clarity of an image and the result of image segmentation, so the concept of information entropy is introduced. Most of the time, it is used as a quantitative standard to evaluate the image.)

说明：  最优化方法（防止限于局部最优等情况时）验证函数，以确定方法的有效性(Test functions)
