您好,再请教一下,(1)把三通道的RGB图像直接计算ssim(2)把彩色图像转换为灰度图像后再对应计算ssim. 这两者有什么区别呢? 2020-08-11 回复喜欢 文章被以下专栏收录 SIGAI 人工智能技术文章 人工智障 就是智障 推荐阅读 后端面试高频问题:Floorplan篇-1 数字IC剑...发表于数字IC剑... SimCSE的loss实现源...

该文献提出了一种取代 MSE, 衡量重建图像和原图的相似性的 metric:Structural Similarity (SSIM),这个 metric 被广泛采纳,至今已经有两万多引用量了。然而遗憾的是,网上很难搜到它的详细中文解读,因此在这里本人尝试记录一下自己的理解。 原文有点啰嗦,作者引用了各种生物学原理,并设计实验证明自己提出的 metric 的...
I want to use SSIM metric as my loss function for the model I'm working on in tensorflow. SSIM should measure the similarity between my reconstructed output image of my denoising autoencoder and the input uncorrupted image (RGB). As of what I understood, for using the SSIM metric in ...
