图像评价是图像处理的一个重要方面，这里提供一种经典的图像评价方法-Image processing image evaluation is an important aspect, here are a classic image evaluation method

图像质量评价，熵、平均梯度、边缘强度、方差等-Image quality evaluation, entropy, average gradient, edge strength, variance, etc.

图像的评价标准有熵、加权峰值信噪比、加权结构相似度、结构相似度、交叉熵、空间频率 这些都有是比较常用的判断标准-FusionEvaluation

几篇经典的图像质量评价方法，包括王周的结构相似度（SSIM）及其改进算法（部分结合局部方差等）.-Several image quality uation of classical method, including the structure similarity of Wang Zhou (SSIM) and its improved algorithm (part of the combination of local vari
