Level compression-based image representation and its applications

摘要

In this paper, a level compression-based image representation (LCBIR) is presented. This new image representation method improves the bintree representation for compressing digital binary images. Then we present a fast search algorithm on the LCBIR, which can support fast search and query in pictorial database. Experimental results show that our search algorithm on the LCBIR is faster than the one on the bintree representation.
