OpenCV手势识别的当前状态? [英] Current state of OpenCV hand gesture recognition?

问题描述

OpenCV中手势识别的当前状态是什么?

What is the current state of hand gesture recognition in OpenCV?

我已经看到了能够检测手势的好例子(例如 https://www.andol. me/1661/)，但是识别手势并执行一些操作(例如操纵屏幕上的对象)似乎要困难得多.

I have seen great examples of being able to detect hand gestures (e.g. https://www.andol.me/1661/) but recognising gestures and performing some action (e.g. manipulating on-screen objects) seems much harder.

有人知道任何例子吗?

谢谢！

推荐答案

我认为OpenCV中唯一支持手势识别的支持正是Luca Del Tongo在您链接的视频中展示的，即

I think the only support in OpenCV for hand gesture recognition is exactly what Luca Del Tongo demonstrated in the video you linked to, namely cvConvexityDefects().

您可能希望使用颜色空间过滤(如视频中建议的那样)并使用ML分类器来检测实际手势来提取手罩.尽管目前尚未在OpenCV中按原样实现 ，但已有几篇论文完成了此操作.

You might want to extract the hand mask using color-space filtering (as suggested in the video), and using ML classifiers for detecting the actual gesture. There have been several papers that have done this, though this is not currently implemented as-such in OpenCV.
