首先将捕捉到的手势图像与背景图像进行Krisch算子图像背景差分,然后把原图像RGB空间转换为HSV空间进行肤色检测[10],得到肤色分割后的二值图像。应用逻辑或运算将差分图像和肤色分割后的图像结合起来。 根据得到的二值图像检测最大连通域,得到手连同部分胳膊区域的二值图像。最后根据手势不同方向,采用不同的方法去掉胳膊...

The implementations are evaluated and compared with a multithreaded C implementation compiled by an optimizing compiler and the results show speed-ups of around 10 × which allows for using PCA on RGB and spectral images in real time. The discussed implementations are made available in a ...
