Abstract(in English) | In this research, we focus on how to track a target region (e.g., head, hand, and etc.) of a person observed in the zoomed-in images. Most of previous tracking methods express a target with a single model. With the single model, however, it is very difficult to continuously track the target region without confusing it and its neighboring similar body-part (e.g., the forearm and the upper arm) because they might have the same texture patterns. In our method, a group of feature points in the target region is extracted and tracked as the model of the target region in order to avoid the miss tracking. Small differences between the neighboring regions can be verified by focusing only on the feature points. In addition, (1) the stability of tracking is improved using Particle filtering and (2) tracking robust to occlusions is realized by removing unreliable ourlier points with a robust estimation technique using random sampling. Experimental results demonstrate the effectiveness of our method even when occlusions occur. |
