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...
这条命令会从Python包索引(PyPI)下载并安装pytorch_msssim及其依赖项。 验证安装是否成功: 安装完成后,您可以通过在Python解释器中导入该库来验证安装是否成功。打开Python解释器(可以通过运行python或python3命令),然后输入以下代码: python import pytorch_msssim print(pytorch_msssim.__version__) 如果没有出现错误,...
pytorch_msssim函数 pytorch mixup 摘要 cutmix和mixup是一种比较重要的数据增强手段,普通的数据增强也只是在照片上修改,增强了对网络提取特征图的能力,cutmix这种就是混合label,增强了fc的学习能力。 cutmix的思想, 只要是用过二张照片,随机的截取一部分,然后换位置,导致label也发生变化。 本来有四种花,我放上去的图...
1、pytorch-msssim pip install pytorch-msssim 安装使用ssim计算结构相似性损失 2、torch torch.seed() 设置随机种子后,每次运行文件输出结果都一样,而不是每次随机函数生成的结果一样 torch.manual_seed() 设置CPU生成随机数的种子,方便下次复现实验结果 torch.squeeze() 对数据的维度进行压缩,去掉维数为1的维度,...
