Abstract (in Japanese) (See Japanese page) 
(in English) Usually, precise discrimination among person's activities requires the recognition of not only the person's posture and action but also the person's surroundings (e.g. objects contacted by the person), and this recognition process assumes that the individual regions of the person and the objects are extracted in advance from a data sequence such as a video sequence. This article proposes an accurate method for extracting the regions of multiple targets (e.g. a person and objects) touching with each other and separating from each other. Our proposed method, which uses an image sequence and a depth sequence, consists of three steps: segmentation of each frame (extraction of subregions), matching subregions between frames (extraction of subregion sequences), and merging subregion sequences. Using several features (e.g., image, depth, and motion features) effectively, our method can improve accuracy in the region extraction of individual targets.
