Efficient contour-based shape representation and matching
2003
Proceedings of the 5th ACM SIGMM international workshop on Multimedia information retrieval - MIR '03
This paper presents an efficient method for calculating the similarity between 2D closed shape contours. The proposed algorithm is invariant to translation, scale change and rotation. It can be used for database retrieval or for detecting regions with a particular shape in video sequences. The proposed algorithm is suitable for real-time applications. In the first stage of the algorithm, an ordered sequence of contour points approximating the shapes is extracted from the input binary images.
