PSNR(Peak Signal to Noise Ratio)是一种评估图像或视频质量的算法,它使用峰值信噪比来度量原始图像和压缩图像之间的差异。PSNR越高,表示压缩图像的质量越好。 PSNR的计算公式如下:

peak_signal_noise_ratio函数返回的是一个浮点数,表示两个图像之间的PSNR值。PSNR值越大,表示两个图像之间的质量差异越小。 你可以将PSNR值用于进一步的分析或比较,比如判断图像处理算法的效果。 (可选)将PSNR值输出或保存到文件: 你可以使用Python的内置函数或文件操作函数将PSNR值输出到控制台或保存到文件中。 py...
Peak signal to noise ratio (PSNR), the de facto universal image quality metric has been widely criticized as having poor correlation with human subjective quality ratings. In this paper, it will be illustrated that the low performance of PSNR as an image quality metric is partially due to its...
The PSNR block computes the peak signal-to-noise ratio, in decibels, between two images. This ratio is used as a quality measurement between the original and a compressed image. The higher the PSNR, the better the quality of the compressed, or reconstructed image. The mean-square error (MSE...
