MS-SSIM is a particularly unstable metric when used for some architectures and may result in NaN values early on during the training. The msssim method provides a normalize attribute to help in these cases. There are three possible values. We recommend using the value normalize="relu" when tra...
UNet3+在编码部分采用的是无重叠的最大池化,这就要求图像下采样过程中的尺寸必须是偶数,在实际操作中可以先考虑最后一层(第5层),例如从下倒上反推依次为8、16、32、64、128。 loss应用问题。作者使用了focal损失函数 , MS-SSIM损失函数 和IoU损失函数 的混合损失函数,但是我在实际使用中并没有严格遵守论文的lo...
ms_ssim_module = MS_SSIM(win_size=11, win_sigma=1.5, data_range=255, size_average=True, channel=3) ssim_loss =1- ssim_module(X, Y) ms_ssim_loss =1- ms_ssim_module(X, Y) Please note that you should maximize ssim to get high quality images, so the loss function is usually 1...

# 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...

i have reimplemented the image segmentation loss functions with pytorch1.10.0 there are binary_crossentropy,dice_loss,focal_loss_sigmod etc all has 2d and 3d version. there are categorical loss functions of crossentropy,dice_loss,focal_loss etc all has 2d and 3d version. MS-SSIM loss and SSI...
