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...

The symmetry number of a tree is defined as the number of nodes of the maximum subtree of the tree that exhibits axial symmetry. The best previous algorithm for computing the symmetry number for an unrooted unordered tree is due to Mitra et al. [8] and runs in O(n) time. In this paper we show an improvement on this time complexity by encoding small trees. Our algorithm runs in time O(n(log logn...

We prove the existence of continuous boundary extensions (Cannon-Thurston maps) for the inclusion of a vertex space into a tree of (strongly) relatively hyperbolic spaces satisfying the qi-embedded condition. This implies the same result for inclusion of vertex (or edge) subgroups in finite graphs of (strongly) relatively hyperbolic groups. This generalises a result of Bowditch for punctured su...

We develop a political-economic model of sovereign debt that shows that income inequality leads to popular pressures on the government to use foreign debt to Þnance a redistribution of income at the expense of productive public investment. Recognizing this fact international lenders impose credit ceilings with the consequence that developing country borrowers invest less and grow slower. ∗We ar...

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 ...
