摘　　要：为实时准确地获取指尖数量,提出一种结合曲率与圆特性的指尖检测方法。首先采用基于肤色与运动检测相结合的方式将手势区域从复杂背景中分割出来;然后对包含手势的图像进行二值化处理,进而对图像进行滤波与形态学处理后提取手势轮廓;再依据曲率的方法提取手势轮廓上的拟指尖点,最后利用指尖点的圆特性将非指尖点去除掉,得到准确的指尖数量。In order to accurately obtain the number of fingertips in real time,a fingertip detection method combining curvature and circular features is proposed.Firstly,the gesture area is segmented from the complex background based on the combination of skin color and motion detection.Then the image containing the gesture is binarized.After that,the image is filtered and processed to extract the gesture contour.The method extracts the cusp point on the contour of the gesture,and finally removes the non-finger point by the circular features of the fingertip point,and obtains the accurate number of fingertips.
