摘要： 针对复杂环境下的手势识别问题，提出一种基于深度图像技术的手势识别方法。利用深度图像信息从复杂环境中提取手势区域，综合手势的表观特征，建立决策树实现手势的识别。对常见的9种手势在复杂背景条件下进行测试，实验结果表明，手势的平均识别率可达到98.4%，速度达到每秒25帧。

Abstract: Aiming at the problem of hand posture recognition from complex backgrounds, this paper proposes a hand posture recognition method based on depth image technoloy. The hand posture region is extracted from complex background via depth image. Appearance features are integrated to build the decision tree for hand posture recognition. Nine common postures with complex background are tested. Experimental results demonstrate that recognition rate is 98.4% and speed rate achieves 25 frames per second.

Key words: hand posture recognition, depth image, appearance feature, complex background, decision tree
