Document Image Coding for Processing and Retrieval

Abstract
Document images belong to a unique class of images where the information content is contained in the language represented by a series of symbols on the page rather than in the visual objects themselves. From this, a new image coding strategy can be designed so as to address some compression and retrieval issues. In this paper we describe a coding methodology that not only exploits component-level redundancy to reduce code length but also expedites efficient data access. The approach uses an image pattern approach that captures image redundancy while providing a natural information index. The approach identifies patterns which appear repeatedly, represents similar patterns with a single prototype, stores the location of pattern instances, and codes the residuals between the prototypes and the pattern instances. Compression results are somewhat competitive but compressed-domain access is clearly superior to competing methods. Furthermore, applications to network-related problems have been considered which show favorable results.Citation
