Webb22 juni 2024 · Histogram Loss. 这时就需要Histogram Loss来实现更好的texture transfer-风格迁移。为什么用Histogram，之前我们说过gram loss不稳定是因为其对所提取对象的分部信息“不感冒”，所以我们利用Histogram来进行修改，因为直方图代表的信息就是分布。 WebbHistogram matching works by forcing the histogram of one image to match as closely as possible the histogram of a second target image. I'm afraid that it won't work on a single image. (There is the exception of using Histogram Matching to force an image to theoretical distribution, like the Gaussian, but that won't help in this case either.)
