【摘要】 本文对基于视觉的手势识别系统进行了研究,给出一种应用于手势识别系统的指尖检测方法。该方法将手指指尖检测分为指尖粗定位和精确定位两部分。首先,通过帧差分、图像二值化等基本图像处理手段分割出感兴趣手的区域,并检测出运动手的最高点,以实现指尖的粗定位;然后,本文利用环形特征模板对指尖进行精确定位。实验结果证明,本文给出的方法可以有效地应用于手势识别系统,指尖定位准确度高,鲁棒性好。更多还原

【Abstract】 In this paper,we propose a method of the finger detection for hand-gesture recognition system.The designation is divided into two parts,including fingertip coarse positioning and fingertip precise positioning.First,we segment our interesting region using of frames difference, image binarization and other basic image processing technology,detect the highest point of the moving hand image and find the rough location of the fingertip,matching the precise location of the fingertip with the template circle character we abstracted previously.The result show that method can be used for hand-gesture recognition system and its positioning accuracy is up to%95 or more with high robustness.更多还原
