Panelists respond to the question, “What does industry need from simulation vendors in Y2k and after?” The panelists include software vendors, simulation modelers from industry, simulation consulting, and academia.

introduction although based on the development literature, achieving sustainable development is one of the most important aims of many developed as well as developing countries, institutional experts argue that development of various institutions could be the base point in these countries. labor market, one of the most important institutions, with a comprehensive look at this market and the geo...

Classification of hyperspectral images is paramount to an increasing number of user applications. With the advent of more powerful technology, sensed images demand for larger requirements in computational and memory capabilities, which has led to devise compression techniques to alleviate the transmission and storage necessities. Classification of compressed images is addressed in this paper. C...

Information hiding in JPEG2000 compressed images is investigated in this research. The challenges of covert communication in this state-of-the-art image codec are analyzed and a steganographic scheme is then proposed to reliably embed high-volume data into the JPEG2000 bitstream. A special mode of JPEG2000 is employed, and its usage and functions are explained and justified. Experimental result...

Scalable encoded information, as in the JPEG 2000 standard, results in files which can be truncated at an arbitrary point and decoded. This work introduces a tractable, yet flexible model appropriate for resource management involving scalably encoded information. At its core is a function yielding a measure of “quality” of the decoded information as a function of the number of bits chosen for d...

In this work, JPEG2000 error resilience options and error concealment strategies are discussed and evaluated. Error resilience options and error concealment strategies have been employed to mimic attacks against selective / partial JPEG2000 encryption schemes. Thus the security evaluation of these selective / partial encryption schemes relies on the proper working of the JPEG2000 error concealm...

This paper presents a new method for remote and interactive browsing of long video sequences. The solution is based on interactive navigation in a scalable mega image resulting from a JPEG2000 coded keyframe-based video summary. The presented system is compliant with the new JPEG2000 part 9 “JPIP – JPEG2000 Interactivity, API and Protocol,” which lends itself to working under varying channel co...
