问题描述
我很想知道如何实现 此处演示的效果 使用 OpenCV.我认为这是某种置换贴图过滤器，但我不是 100% 确定.
I'm curious to know how one can implement the effect demonstrated here using OpenCV. I think it's some sort of displacement map filter but I'm not 100% sure.
该页面完全加载后，四处移动鼠标以查看背景图像移动(这是我正在寻找的效果).
After that page has fully loaded, move the mouse around to see the background image move (it's the effect I'm looking for).
有可能吗?我该怎么做?
Is it possible? How would I go about doing it?
推荐答案
问这个问题已经快2年了，我觉得是时候回答了:可以找到使用OpenCV实现这个过滤器的源代码在我的 GitHub 存储库 中.
It's been almost 2 years since I've asked this question and I think it's time to answer it: the source code that implements this filter using OpenCV can be found in my GitHub repo.
实施基于 Adobe Flash DisplacementMapFilter.
我推荐人们阅读另一个教程:Psyark 的 DisplacementMapFilter 教程.它很旧但很准确.
There's another tutorial I recommend people to read: Psyark’s DisplacementMapFilter Tutorial. It's old but accurate.
