<p>Visual object tracking techniques are widely required by many vision applications. The color-based particle filter is known as one of useful methods for robust object tracking. However, the conventional color-based particle filter has a problem that it is not robust against self-occlusion. Self-occlusion occurs when a part of a target object is hidden by itself from a camera. When the target object moves or rotates, a part of the target disappears because the self-occlusion occurs and other part appears because the self-occlusion is resolved. The conventional color-based particle filter often fails to follow such a change of the target's appearance due to self-occlusion during the tracking process. In this paper, we propose a novel method for robust object tracking against the self-occlusion. The proposed method is based on the color-based particle filter, and it also uses depth information obtained by an RGB-D camera. When the self-occlusion occurs and the target's appearance changes, the proposed method extracts a region for the target object in the input image by the graph cuts based on depth information. However, this process often includes unnecessary regions, especially when some objects are close to the target. Then, the proposed method distinguishes the region for the target from unnecessary ones by investigating expanse of colors around the target. Therefore, the target model is correctly updated and the robust tracking is achieved. In order to verify the effectiveness of the proposed method, we carried out an experiment to compare the proposed method with the conventional one. Experimental results show that the proposed method works well.</p>

It is important for teacher to design a class while grasping the state of students understanding. In order to grasp the state of students, I need an integrated approach with the state of students understanding and knowledge structure and collaborative learning. So I propose a new simulation that is built with a doubly structural network model. It has an internal network and a social network. An internal network is built from the knowledge structure and the state of students understanding. A social network is built from cooperative relationship in the class. I address two problems. The first is consideration of the effects of teaching strategy given to learning. The second is consideration of the effects of placement given to learning. I found these results, 1) differences in teaching strategy give a change in the learning effect, and teaching strategy that this simulation produces has a high educational effect, 2) if a teacher gives a knowledge only once, dropouts tend to occur, 3) placing the students distributed tends to have the effect of education than placing the students centralized.
