A JPEG 2000 compound image file reader/writer and interactive viewer

JPEG 2000 is the emerging image compression standard. This International Standard defines a normative but optional file format for storing compound images using the JPEG 2000 file format family architecture. A compound image is an image that may contain scanned images, synthetic images or both, and that preferably requires a mix of continuous tone and bi-level compression methods. Besides defining a binary container for a mix of continuous-tone and bi-level images, this format defines a composition model that describes how the multiple images are combined to generate a compound image. This composition model is based on the multi-layer Mixed Raster Content (MRC) imaging model. A key feature of JPM is its support of fragmented JPEG 2000 codestreams to enable progressive and interactive rendering in web applications. In this paper, we describe the design and implementation of JPM Reader/Writer and a prototype compound image file interactive viewer, in the context of browser plug-ins, and Web Service applications. Examples will be given and results will be provided.

An Evaluation of Currently Available JPEG 2000 Software Implementations

JPEG 2000 is the emerging image compression standard. The base standard (Part 1) was approved in January 2001. Several corporations, research organizations, and individual parties are already offering software implementations of, at minimum, Part 1 of the specification. This paper describes the test metrics and results for some of the currently available JPEG 2000 software implementations. The software implementations are also compared against the JPEG 2000 Verification Model (VM) and the Independent JPEG Groups JPEG implementation (IJG). The evaluation testing is performed under both the Unix (Solaris) and Windows operating systems. Results will be presented from the metrics categories mentioned above.

A Document Viewer for Handheld Devices using JPEG 2000 Technology

JPEG 2000 is the emerging image compression standard. Part 1 of the standard was approved in January 2001, and software implementations of JPEG 2000 are starting to appear in the industry. JPEG 2000 might rapidly become one of the more commonly used compressed image file formats. What then would be an ideal way to showcase the rich feature set that JPEG 2000 offers? In this paper we describe how JPEG 2000 technology was enabled on a handheld device, including the manner by which it was designed and implemented, the software and hardware tools that were used for the development, the target PDA (Personal Digital Assistant) and operating system, the roadblocks that were encountered along the way and subsequently overcome, and the results and feedback for the completed application, which was demonstrated on the floor at Comdex 2001.
