Abstract:
1. An apparatus for estimating a joint structure of a human body, comprising: a multi-view image acquisition unit for receiving multi-view images acquired by capturing a human body; a human body foreground separation unit for extracting a foreground region corresponding to the human body from the acquired multi-view images; a human body shape restoration unit for restoring voxels indicating geometric space occupation information of the human body using the foreground region corresponding to the human body, thus generating voxel-based three-dimensional (3D) shape information of the human body; a skeleton information extraction unit for generating 3D skeleton information from the generated voxel-based 3D shape information of the human body; and a skeletal structure estimation unit for estimating positions of respective joints from a skeletal structure of the human body using both the generated 3D skeleton information and anthropometric information, wherein the skeleton information extraction unit comprises a medial surface voxel extraction unit for extracting medial surface voxels, which are a minimum number of surface voxels enabling representation of a 3D shape of the human body, from surface voxels in the 3D shape information of the human body.
