闲逛github看到的新手势软件
它的识别算法有人看得懂吗?(我没看懂)
Shape recognition : compare angles, get the average of the angles differences :
The calculated difference is approximately the area between the 2 curves of angles (mod 2𝜋) visible on the right of the above image.
Get the minimum difference by shifting a curve horizontally: try removing the beginning or the end, by +/- 10 % max offset (max 20 try).
