| Abstract(in English) | Active contour models (snakes) are useful for tracking contours of deformable objects compared with conventional approaches based on segmentation and motion measurement. However, Snakes can not follow correct contours of multiple objects when they overlap. This report describes a new split-and-merge contour model based on detecting self-crossing and mutual-crossing of the models. The proposed method can find occlusions of multiple objects by detecting mutual-crossing of different models which extract different objects. Multiple different models which are mutually crossing are merged into a single model. The merged model is split into multiple models when overlapping objects leave away from each other. In order to prove the effectiveness of the method, we apply our model to extracting walking persons in a room scene. |
