Decomposition of partly occluded objects based on evaluation of figural goodness

In this paper, we propose an object decomposition system which can deal with partly occluded objects. In order to develop shape-independent object decomposition, the system combines different types of contour completion methods, namely, line completion, curve completion, line-symmetry completion and rotational symmetry completion. The system evaluates figural goodness of each completion pattern generated by these completion methods from the aspect of simplicity and symmetricity, and then selects the best one to output. From the experimental results, we have confirmed that the proposed system can correctly decompose objects from an input image.
