用帧差法提取候选目标区域,构造皮肤颜色评价函数,对当前帧候选目标区域的所有像素进行评价,再对肤色评价值进行soble变换,得到候选目标区域的边缘,分别将边缘作水平和垂直投影,从而实现人手定位,进而跟踪人手运动轨迹。

Possible object areas are selected through using frame differentiation method. Human color evaluation function is constructed to evaluate the pixels in possible object areas. Soble transformation are done to the evaluation function values. As a result, edges of possible objects are gotten, which are projected to the horizontal axis and ver- tical axi...
