PSNR is a variant of SNR commonly used in digital image and video compression. It measures the ratio between the maximum possible power of a signal and the power of the distortion or noise that affects the quality of that signal. PSNR is defined as: Where "MAX" is the maximum possible pi...
image1和image2是需要计算PSNR的两个图像数据。 data_range参数用于指定图像数据的取值范围。对于8位图像,通常取值为255。 获取并处理peak_signal_noise_ratio函数的返回值: 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...

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...
peaksnr = psnr(___,'DataFormat',dataFormat) [peaksnr,snr] = psnr(___)Description peaksnr = psnr(A,ref) calculates the peak signal-to-noise ratio (PSNR) for the image A, with the image ref as the reference. A greater PSNR value indicates better image quality. example peaksnr = psn...

The effect of packet losses over error-prone networks on visual quality of distributed video contents, estimated through subjective opinion and PSNR as an objective measure is analysed. It is shown that, within a fixed content, the variation of PSNR is a reliable indicator of the variation of ...
