Title

¬An approach to image retrieval based on shape

Abstract

In content based image retrieval systems, it is necessary to find a metric to index shapes of objects of the images. The metric should be unique to each shape, regardless of size and orientation. A similarity measure is also needed which should reflect the perceptual similarity. Chain codes have been used for shape description in earlier research, but chain codes are non invariant to shape size and orientation. Introduces a method to eliminate the inherent non variance of chain codes to obtain unique chain codes for shapes. The shape index is derived from this unique chain code representation. Discusses the shape distance and similarity measures based on the shape index. Indexing and retrieval procedures should be applicable to large image databases
