This paper presents an innovative way to combine edge detection and linking using the wavelet representation and image fusion. We describe how to detect and link edges in connection to horizontal and vertical orientations selectivity of the human visual system. We develop a framework with three stages: decomposition, recomposition, and fusion. In recomposition stage, we reconstruct both horizon...

Totally asymmetric simple exclusion processes, consisting of two coupled parallel lattice chains with particles interacting with hard-core exclusion and moving along the channels and between them, are considered. In the limit of strong coupling between the channels, the particle currents, density profiles and a phase diagram are calculated exactly by mapping the system into an effective one-cha...

In this paper an optoelectronic system for fast grey-level image decomposition into binary slices is presented. To perform thresholding we take advantage of the differential nature of optical thyristors and compare the light level of the image pixels with that of a reference intensity. For the input a grey-level image was generated using a liquid crystal spatial light modulator (SLM) and, for t...

A new feature extraction approach based on elastic meshing and directional decomposition techniques for handwritten Chinese character recognition (HCCR) is proposed in this letter. It is found that to decompose a Chinese character into horizontal, vertical stroke, left slant and right slant directional sub-pattenrs is very helpful for feature extraction and recognition. Three kinds of decomposi...

This paper adopts a hierarchical multilayer/ multilevel approach for the allocation, management and control of B-ISDN resources. This approach seems appropriate to present a vertical decomposition of control layers, having different time-scales in addition to a horizontal decomposition, derived from the geographical distribution of control units. The paper outlines the layers proposed and expla...

A seismic volume of a certain stratigraphic layer may be decomposed into components for channel analysis. In the first case study of stratigraphic interpretation, the relative amplitude of the first component outlines the channel. The relative amplitude of the second component discovers different lithological or stratigraphical features inside the channel. The relative amplitude of the third co...

We consider geometric decompositions of aspherical 4manifolds which fibre over 2-orbifolds. We show first that no such manifold admits infinitely many fibrations over hyperbolic base orbifolds. If E is Seifert fibred over a hyperbolic surface B and either B has at most one cone point of order 2 or the monodromy has image in SL(2,Z) then E it has a decomposition induced from a decomposition of B...

This paper presents a HTTP based multimedia content streaming architecture able to provide large scale WebTV services to end users connected over several access network technologies. The architecture features smooth Rate Adaptation, context Personalization information (Channel Suggestions), fast program channel switching, Network Portability (Vertical Handover) and Terminal Portability capabili...
