Abstract

Compound document images contain graphic or textual content along with pictures. They are a very common form of documents, found in magazines, brochures, Web-sites, etc. We focus our attention on the mixed raster content (MRC) multi-layer approach for compound image compression. We study block thresholding as a means to segment an image for MRC. An attempt is made to optimize the block-threshold in a rate-distortion sense. Rate-distortion curves are presented to demonstrate the performance of the proposed algorithm.
