We present a new image compression technique called ''DjVu''that is specifically geared
towards the compression of highresolution, high-quality images of scanned documents in …

ASSistant Examiner David Rosenblum 57 ABSTRACT A method in which first and Second
representations of a document are provided, for example, by being made avail able on one …

We present a method for both lossless and lossy compression of bi-level images that consist
mostly of printed or typed text. The key feature of the method is soft pattern matching, a way …

Aprocessor is provided With a? rst set of digital information that includes a? rst, resolution-
independent structured rep resentation of a document. This? rst representation is one from …

Textual image compression is a method of both lossy and lossless image compression that
is particularly effective for images containing repeated sub-images, notably pages of text …

Image compression usually considers the minimization of storage space as its main
objective. It is desirable, however, to code images so that we have the ability to process the …

A two-stage method for compressing bilevel images is described that is particularly effective
for images containing repeated subimages, notably text. In the first stage, connected groups …

(57) ABSTRACT A processor is provided with a first Set of digital information that includes a
first Structured representation of a document. From the first Set of digital information, the …

In this paper, we describe a compression and representation scheme which exploits the
component-level redundancy found within a document image. The approach identifies …

Purpose–The purpose of this paper is to propose a lossy/lossless binary textual image
compression method based on an improved pattern matching (PM) technique …
