Detailed profile of the context formation process in EBCOT is analyzed to get an insight into the characteristics of the ope...

This paper proposes an integrated solution for smart delivery of video surveillance data. The system is developed within the IST project WCAM "Wireless Cameras and AudioVisual Seamless Networking" which is presented as well [1]. The main feature of our system is it includes smart video coding based on automatic scene analysis and understanding. Specifically, the segmentation results are used fo...

This paper proposes a quantization-based image-quality guaranteed watermarking (IQGW) method using a nonorthogonal discrete wavelet transformation. An IQGW method generates watermarked images of a desired image quality for any image, neither with trial and error nor with image-dependent parameters. To guarantee the image-quality, the proposed method adjusts the energy of the watermark sequence ...

The specifications of Motion JPEG 2000 (MJ2) and related documents in the JPEG 2000 family are analyzed, to identify and assess the multiple mechanisms available for storing metadata within a MJ2 file and the types of metadata that can be so accommodated. Adequate mechanisms seem to exist for associating metadata with the production as a whole, individual tracks, and individual frames. In those...

I discuss the physics reach of a fixed-target charm experiment which can reconstruct >10 charm decays, three orders of magnitude beyond the largest extant sample. Such an experiment may run at Fermilab shortly after the Year 2000. In addition to “programmatic” charm physics such as spectroscopy, lifetimes, and tests of QCD, this “Charm2000” experiment will have significant sensitivity to new ph...

The Image Reduction and Analysis Facility is a scientific image processing package widely used throughout the astronomical community. IRAF has been developed and distributed by the National Optical Astronomy Observatory in Tucson, Arizona since the early 1980’s. Other observatories and projects have written many dozens of layered external application packages. More than ten thousand journal art...

JPEG2000 is the new standard for the compression of still images. Its objective and subjective image quality performance is superior to existing standards. In this paper the Part I of the JPEG2000 standard is presented in brief, and its implementation complexity on different computer platforms is reported.

In the terms of operational calculus the probability characteristics of direct and reverse residual renewal time of alternating renewal process, where renewal time depends on life-time, are found. 1. Definitions, Motivations and Formulation of the Problem 1.1 According to [1] let’s consider a system which fails after random life-time X1 and is fully renewed after the lapse of random time Y1. Th...
