Color image representation using bsp

This paper presents a novel approach to colour image representation using Binary Space Partitioning (BSP) Tree. In the past, BSP tree has been used to represent grey scale images. Extending the method to colour images is however not straightforward. We propose to apply the moment-preserving thresholding technique to binarize the colour image, and determine the partitioning lines from the binary image based on a goodness-of-fit criterion. We present the results of this new technique and its applications to image coding. We also discuss the potential of the application of the technique to content based image indexing and retrieval.
