图像稳定/对齐算法 [英] Image stabilization/alignment algorithm

问题描述

从我在网上看到的，图像稳定是使用格雷编码的位平面匹配。但是，我无法理解它（格雷码本身并不复杂，而是其余部分）。任何人都可以向我指出一个关于这个主题的资源（或另一种稳定的稳定方法），它略低于大多数发表论文的水平吗？示例代码胜过抽象广义方程式。

From what I have read on the web, one of the most efficient algorithms for image stabilization is to use Gray coded bit plane matching. However, I'm having trouble understanding it (Gray codes themselves are not that complex, it's the rest of it). Can anyone point me to a resource on this subject (or another good method of stabalization) that is a little below the level of most published papers? Sample code beats abstract generalized equations.

出于我的目的，视频中没有平移或缩放，帧中没有移动对象。

For my purpose, there will be no panning or zooming of the video and no moving objects in the frames.

推荐答案

你可以先尝试一些简单的方法，我最近在这里提出了一些建议：使用OpenCV进行视频稳定

You can try some simple approaches first, I've suggested some recently here: Video Stabilization with OpenCV

在您的情况下（没有平移，没有缩放，静态场景），相位相关可能已经足够且它相当容易（参见维基百科）。
如果我没记错的话，有几个可用于avisynth的视频稳定滤波器/插件使用相位相关 - 你可以先试用它们。

In your case (no pan, no zoom, static scene), phase-correlation might be already sufficient and it's quite easy (see e.g. wikipedia on that). If I recall correctly, there are several video stabilization filters/plug-ins available for avisynth that use phase-correlation - you can try them out first.

根据我的需要，我已经实现了一个简单的工具，它可以使SURF / Homography路线对齐多个图像（对齐图像，而不是视频）。您可能想尝试一下，看看这是否满足您的需求： http://web.archive.org/web/20101004234404/http://ioctl.eu/wiki/applications/ImageAlign （嘿，我希望代码仍在运行...... ）

For my needs, I've implemented a simple tool that goes the SURF/Homography route to align several images (aligns images, not videos). You might want to try that out to see if this suffices your needs as well: http://web.archive.org/web/20101004234404/http://ioctl.eu/wiki/applications/ImageAlign (Heh, I hope that code still runs...)
