pytorch structural similarity (SSIM) loss. Contribute to Fire-friend/pytorch-ssim development by creating an account on GitHub.
This small utiliy provides a differentiable MS-SSIM implementation for PyTorch based on Po Hsun Su's implementation of SSIM @https://github.com/Po-Hsun-Su/pytorch-ssim. At the moment only the product method for MS-SSIM is supported.
SSIM值越大代表图像越相似,当两幅图像完全相同时,SSIM=1。所以作为损失函数时,应该要取负号,例如采用 loss = 1 - SSIM 的形式。由于PyTorch实现了自动求导机制,因此我们只需要实现SSIM loss的前向计算部分即可,不用考虑求导。(具体的求导过程可以参考文献[3]) 以下是代码实现,来源于github [4]. 1importtorch2i...

不过MSELoss 存在一些问题,所以还可以用SSIMLoss,SSIMLoss目前得通过一个第三方包来使用pytorch_ssim,值得注意的是这个包目前通过pip安装使用的话会有问题,目前的解决方案是直接把github上的代码下载下来放到项目里面,使用方式很简单 #定义ssim_lossssim_loss=pytorch_ssim.SSIM(window_size=11)#计算lossloss=1-ssim_...

Hi, I use both pytorch_mssim.ssim and skimage.measure.compare_ssim to compute ssim, but the results are different. For example, ssim evaluation on an image sequence: pytorch_msssim.ssim: [0.9655, 0.9500, 0.9324, 0.9229, 0.9191, 0.9154] s...
