摘要
研究并提出了一种基于人体轮廓图像确定人体关节位置的方法。首先利用能量函数从人体轮廓中抽取人体的虚拟骨架,然后利用所定义的标准人体骨架模型中给出的确定人体虚拟骨架中的一个点是否为关节点的三个规则以及人体解剖学的相关知识确定关节的位置。实验结果表明,该算法行之有效。它无需对图像中的人体在运动和颜色等方面附加限制条件;同时,对人体轮廓图像中的噪声亦有很好的抑制作用,这一特点使得它对人体轮廓提取的精度要求较低,在复杂的背景下具有较的性能。
A method for articulated-pose identification from the silhouette of a human body is presented. The method employs an energy function to extract a dummy skeleton of a human body from the silhouette, and then estimates the position of the joints by the knowledge of anthropotomy. Three rules are given to the standard human skeleton model, which are helpful to judge whether a point on the skeleton is a joint or not. The experimental results show that the method is effective because it requires no additional restrictions on the motion and color of a human body. The method is robust against the noise in the silhouette having complicated background.
