pHash 最近邻和颜色直方图最近邻之间的区别?
我希望创建一系列尽可能相似的动画照片。在研究过程中,我遇到了两种方法:
- 生成图像的 pHash 并使用散列的汉明距离进行最近邻分析。
- 创建颜色直方图并使用欧几里德距离进行 n 维最近邻。
许多人对 https://stackoverflow.com/ 发表评论questions/6971966/how-to-measure-percentage-similarity- Between-two-images 问题声称这两个过程本质上是相同的。我正在寻找对此的更多见解。它们看起来像是不同的过程。
想法?
I'm looking to create an animated series of photos that are as similar as possible. While researching, I've come across two methods:
- Generate a pHash of the images and do a nearest neighbor using the Hamming distance of the hash.
- Create color histograms and do an n-dimensional nearest neighbor using Euclidian distance.
Many people who have been commenting for the https://stackoverflow.com/questions/6971966/how-to-measure-percentage-similarity-between-two-images question claim that the two processes are essentially the same. I'm looking for a little more insight on this. They seem like different processes.
Thoughts?
