【摘要】 本文针对人体运动视觉分析中的行为理解和分析等高层视觉问题进行分析,研究了一种静止摄像机条件下的行为理解和分析的算法,它以运动序列中的关键帧为基础,针对关键帧提取人体的骨架信息,然后通过Hu不变矩来提取特征,最后组成特征向量,通过对HMM模型的训练来识别特定运动序列的语义。更多还原

【Abstract】 This paper focuses on visual analysis of human movement and the understanding of high level visual problems. It gives an algorism to comprehend and analysis people’ s movement if the camera is not moved. We present an algorithm based on key frames, this technique can be more effective in the original sequence by reducing the interference of detection and identification.更多还原
