An entropy based segmentation algorithm for computer-generated document images

Abstract

This paper presents an efficient compression-oriented segmentation algorithm for computer-generated document images. In this algorithm, a document image is represented in a block-based multiscale pyramid. Then, image blocks will be characterized based on their entropy values of the intensity histogram, and the entropy distribution are assumed to be Gaussian… (More)
