ssim_index
- 计算两幅图像的相似度，与psnr有所区别，根据两幅图像的纹理结构来判断两幅图像的相似度-Calculate the similarity of two images, and psnr be different, according to the texture structure of the two images to determine the similarity of two images
psnr
- 计算图像的均方误差和峰值信噪比，来评价图像的质量-MSE is calculated images and peak signal to noise ratio, to evaluate the quality of the image
PSNR
- 峰值信噪比的源函数，数值越大，表示图像越清晰，反之，图像模糊。-Source function peak signal to noise ratio, the greater the value, the image is more clear, on the contrary, the image is blurred.
去雾图像评价
- 7种去雾图像评价函数，包括PSNR/WPSNR、图像信息熵、图像对比度、平均梯度、均值等客观评价函数。
