我已经测试过pytorch 1.6没有这个问题。 我研究了piqa库的 ,这使我实现ssim和ms-ssim的速度比以前快了一些。 加速。 仅在GPU上测试。 losser1是 268fc76 losser2是 881d210 losser3是 5caf547 losser4是 1c2f14a losser5是 abaf398 abaf398 在pytorch 1.7....
阅读论文《Loss Functions for Image Restoration With Neural Networks》 ,L1损失函数获得的图像质量会更好。这里论文调研了L1损失,SSIM和MS-SSIM,并将L1损失函数和MS-SSIM结合起来构建新的损失函数。但是目前为止,基于SSIM的指标还没有应用到损失函数中...;xy+C2σx2+σy2+C2(2)=l(p)⋅cs(p)(3)SSIM的...
PAD-Net: A Perception-Aided Single Image Dehazing Network guanlongzhao/single-image-dehazing • 8 May 2018 In this work, we investigate the possibility of replacing the $\ell_2$ loss with perceptually derived loss functions (SSIM, MS-SSIM, etc.) 1 Paper Code ...
