摘要： 提出了一种基于手势关键点的手势识别算法。从经过二值化处理的字母手势图像中提取重心,并由字母手势图像的边缘信息中提取字母手势的关键点(指根和指尖)。借助Hausdorff Distance(HD),运用关键点的信息对手势进行识别。

Abstract: This paper presents a gesture recognition algorithm.Feature pixels are extracted as feature vectors from gesture patterns and feature vectors are used to match with feature vector of gesture library by means of Hausdorff distance to recognize gesture patterns.
