Rapid and Brief Communication Graph matching for object recognition and recovery

A robust skeleton-based graph matching method for object recognition and recovery applications is presented. The ob- ject model uses both a skeleton model and contour segment models, for object recognition and recovery. The presented skeleton-based shape matching method uses a combination of both structural and statistical methods that are applied in a se- quential manner, which largely reduce the matching space when compared with previous works. This also provides a good alternate means to alleviate di6culties encountered in segmentation problems. Experiments of object recovery using real biomedical image samples have shown satisfactory results. ? 2003 Pattern Recognition Society. Published by Elsevier Ltd. All rights reserved.
