Web网上找了很多关于PSNR和SSIM的计算，很多结果算出来都不一样，公式都是普遍的，如下： 现在总结下造成结果差异的原因。 PSNR的差异： 1.灰度图像：灰度图像比较好计算，只有一个灰度值。 2.彩色图像： (a) 可以将分别计算R,G,B三个通道总和，最后MSE直接在原公式上多除以3就行（ opencv官方代 码 是这么做的，与 matlab直接计算结果 是一样的）。 (b) … WebJul 28, 2024 · ESPCN (Efficient Sub-Pixel CNN), proposed by Shi, 2016 is a model that reconstructs a high-resolution version of an image given a low-resolution version. It leverages efficient "sub-pixel convolution" layers, which learns an array of image upscaling filters. In this code example, we will implement the model from the paper and train it on a ...
