A Study on Shape Matching of Two-Dimensional Object using Relaxation

Relaxation을 이용한 2차원 물체의 형상매칭에 관한 연구

This paper prrsents shape matching of two-dimensional object. This shape matching is applied to two-dimensional simple c10sedcurves represented by polygons. A large number of shape matching procedures have proposed baseed on teh view that shape can be represented by a vector of numerical features, and that this representation can be matched using techniques from statical pattern recognition. The varieties of features that have been extracted from shapes and used to represent them are numerous. But all of these feature-based approches suffer from the shortcoming that the descriptor of a segment of a shape do not ordinarily bear any simple relations hip to the description for the entire shape. We solve the segment matching problem of shape matching, defined as the recognition of a piece of a shape as approximate match to a part of large shape, by using relaxation labeling technique.

본 논문은 2차원 물체의 형상 매칭에 관한것으로 다각근사화된 단순 2차원 물체에 적용하였다. 많은 형상 매칭 방법론이 수학적 벡터의 의현에 기초를 두고 확솔적인 패턴 인식을 사용하고 있다. 유출된 형상의 다양성과 많은 데이타량은 형상의 전체적인 구조의 관계를 나타내는데 단점을 갖고 있다. 본 논문에서는 영상을 다 각근사적 과정를 통하여 Relaxation 라벨링 기술을 이용함으로써 형상 매칭의 지점을 해결하였다.
