摘要：Shape is most important visual feature of an image. Most of the region based shape descriptors are complex in nature and computationally intensive. In this paper, we analyzed various raster models like circular, square by exploring exterior contour information with the help of grid based approaches. Spiral models are introduced in this paper with a comparative study. We compute a one dimensional shape vector from two dimensional shape region. The retrieval performance of these raster models are evaluated over 400 test images.
