Navigation through large microscopical images is a potential benefit for histology or pathology teaching, quality of diagnosis in pathology or communication between pathologists in some telemedicine applications. However, the size of this kind of images is prohibitive for navigation with conventional techniques. This paper presents a system which constructs large microscopical images and descri...

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.

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...
