loss function: 在分类问题中,输入样本经过含权重矩阵θ的模型后会得出关于各个类别的分值,如何通过分值与样本的标签来得到我们对模型的满意程度就是Loss function的主要工作了。训练过程中通过调整参数矩阵θ来降低loss,使用模型更优。多分类问题中常用Softmax分类器与多类SVM分类器。 Softmax分类器 Softmax与l...
一种专注于边缘以及精细结构分割的网络,同时提出一种混合loss,对这篇论文感兴趣的同学,可以看一下本文的详细总结:https://share.mubu.com/doc/3XISi_xs1heℓk=ℓkbce+ℓkssim+ℓkiou 二元交叉熵BCE、结构相似性SSIM和IOU损失,分别指导网络学习三级(即像素级、补丁级和图像级)层次结构表示。在边缘结构分...

下面的链接是计算 SSIM 的 pytorch 代码: SSIM Pytorchgithub.com 如果看懂了 skimage 的代码,相信你肯定也能理解这个代码。该代码只实现了高斯加权平均,没有实现普通平均,但后者也很少用到。 下面的 GIF 对比了 MSE loss 和 SSIM 的优化效果,最左侧为原始图片,中间和右边两个图用随机噪声初始化,然后分别用...
Of course, a more complete/general version of ssim or ssim_loss would require a bit more work, but I'm willing to give it go if there's a home for it. Member ToucheSir commented Jan 21, 2023 It looks like CUDA compatibility comes down to Distances.jl, where the problem seems to ...
谢邀，个人认为这个问题涉及到多任务学习的概念，建议看看文章《Multi-task learning using uncertainty to weigh losses for scene geometry and semantics》，github上的pytorch实现：automaticweightedloss 感觉
Ecole des Ponts和Berkeley合作的RANSAC-Flow,一种应用于图像对齐的自监督方法:1. 用off-the-shelf 特征+ RANSAC 估测一个粗略对准(coarse alignment)2. 在粗略对准的基础下,再设计一个轻量级CNN 进行精细地对齐。Loss主要是 图像重建Loss(SSIM)和Flow一致性(Consistency),没有额外的监督信息。3. 文章提供了链接...
In this paper, we add the structure similarity index measure (SSIM) loss factor and perceptual loss into the basis CycleGAN's loss function for keeping rich structural information. The tentative study demonstrated the potential of the SAR and the optical image translation based on the CycleGAN. ...
