| Abstract(in English) | A visual model for object detection is proposed. The dynamics of the proposed model is based on the computational principle of active contours, which is a fundamental method for various image processing. A redefined level set function is utilized in order to model object-detecting neurons. An initial value problem of active contours is solved by introducing a visual property revealed by cognitive psychological experiments. Numerical experiments show that the technical effectiveness of the proposed model. The proposed model detects objects with complex topologies, which has not been dealt with by existing methods. Psychophysical experiments were performed in order to investigate the relation between figure-ground perception and visual attention. It is shown by other numerical experiments that the proposed model equipped with visual attention accounts the psychological experimental results. |
