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...
