Optimizing Block-Threshold Segmentation for MRC Compression

چکیده
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 mean 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.

متن کاملMixed Raster Content for Compound Image Compression
Mixed raster content (MRC) is described in the following report. It is a compression method which will be described here for compression of compound images (images containing both, continuous tone images and binary text) [1]. It uses a multi-layer, multi-resolution representation of a compound document. Instead of using a single algorithm, it uses multiple compression algorithms, including the ...
متن کاملCompression of Compound Documents
Compound (or mixed) 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. Because of the very distinct nature of those two image classes (text/graphics vs. pictures), their compression invariably involves multiple compression systems and a region segmentation (classification) method. We rev...
متن کاملRate-distortion-based segmentation for MRC compression
Effective document compression algorithms require scanned document images be first segmented into regions such as text, pictures and background. In this paper, we present a document compression algorithm that is based on the 3-layer (foreground/mask/background) MRC (mixture raster content) model. This compression algorithm first segments a scanned document image into different classes. Then, ea...
