この辺り。
最初全くわからなかったんだけれど、Integral Image というのを使って、ある範囲内の輝度の積分を高速に計算しています。

Feature Detection using Integral Images
物体認識とかって技術の裏では、こういった算数のような細かい計算の高速化が大きなブレイクスルーだったりするんだなー、って感動した。

    Do you happen to know if anybody has ported the hand recognition portion of OpenCV to Flash/AS3?

    Sorry, no I didn’t know that OpenCV had something for hand recognition.

    Hey Mash, it’s a great port, it had helped me a lot with my project. Do you know how difficult would be to port eye detection part of OpenCV to AS3?
