conda install -c conda-forge pytorch-msssim 安装完成后,重新运行你的代码,检查是否还会出现同样的错误。检查ssim函数在pytorch_msssim库中的正确用法: 根据参考信息,pytorch_msssim是一个用于计算图像结构相似度(MSSSIM)的PyTorch模块。确保你使用的函数名ssim是正确的,因为pytorch_msssim通常提供的是msssim函数,而不...

# SSIM 和 MSSIM 的计算较为复杂,在这里,我们直接调用 pytorch-msssim 的接口来进行计算 ssim = pytorch_msssim.SSIM(data_range=1.0, size_average=True, channel=3) mssim = pytorch_msssim.MS_SSIM(data_range=1.0, size_average=True, channel=3) # 实例化 ssim = pytorch_msssim.SSIM(data_range=1.0...

MSSSIM 全称是多尺度结构相似性(Multi-Scale Structural S Similarity),它其实是建立在 SSIM(结构相似性)的基础之上发发展而来的。SSIM 这个概念最早是由 Wang 等人在 2004 年提出来来的。当时人们在衡量图像相似度时,传统的方法像均方误差(MSE E)虽然简单直接,但它有个大问题,就是只考虑了像素值的差异...
I would like to ask about the reproducibility issues with SSIM and MS-SSIM. I am considering using MS-SSIM as a loss function to supervise my model's training. However, I have noticed that when using pytorch_msssim for SSIM and MS-SSIM, ...

Hi, Thanks for this tool. 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, 0.9...
