手势识别与动作摄像头视频 [英] hand gesture recognition with camera video in actionscript

问题描述

我想要实现使用ActionScript 3的Flex应用程序：用相机和的美德按钮（如图像）的摄像头，可以将他的手越过的美德键字段，以触发按钮。现在我的溶液以下这样：捕捉按钮字段中erery帧得到的BitmapData，并计算的BitmapData的灰度求和，如果两帧之间的差异大于一个给定值，则火 的按钮。实际上，它可以工作，但它是非常合理的，背景，更坏的照明条件下，当有一个以上的按键，人们常常通过misdike触发按钮。任何更好的想法吗？有没有第三，帕蒂libary为了这个目的？

I want to implement an flex application using actionscript 3: with the camera and the virture buttons(like a image) in the camera, one can move his hand to pass over the virture button field in order to fire the button. Now my solution is following this way: capture the button field in erery frame to get a bitmapdata, and calculate the gray-scale summation of the bitmapdata, if the difference between the two frames is greater than a given value, then fire the button. Actually, it could work, but it is very sensible to the lighting condition of the background, worse, when there are more than one buttons, people often fire the button by misdike. Any better ideas ? Is there any 3rd-paty libary for this purpose ?
