Non-linear camera models are playing an increasingly important role in computer graphics, especially in image based rendering and non-photorealistic rendering. We introduce ARTcams as simple non-linear cameras, which are unique in combining both geometric projection and non-geometric attributes such as colour into a single model. The geometric component of an ARTcam subsumes many contemporary n...

This paper describes the Junctionality oj a 3D Graphics Raster Processor called TAYRA. TA YRA consists in the most part oj Graphics Raster Pipeline with five major external interfaces: PCI Master/Target, Depth, Texture, Colour and Video Interfaces. The Graphics Raster Pipeline perform'S' all the major OpenGL style (not necessarily compliant) raster functions: scan conversion; lines, spans, tria...

in this research we described the effective hamiltonian theory and applied this theory to the calculation of current-current (q1,2) and qcd penguin (q3,…,6) c quark decay rates. we calculated the decay rates of semileptonic and hadronic of charm quark in the effective hamiltonian theory. we investigated the decay rates of d meson decays according to spectator quark model (sqm) for the calculati...

We present Subversion Statistics Sifter, a visualisation and statistics system for exploring the structure and evolution of data contained in Subversion repositories with respect to both developer activity and source code changes. We support a variety of visualisation techniques, including statistical graphics and graph plots. We exploit the inherent hierarchical structure of software archives ...

Visibility computation is often the bottleneck when rendering indirect illumination. However, recent methods based on instant radiosity have demonstrated that accurate visibility is not required for indirect illumination. To exploit this insight, we cluster a large number of virtual point lights – which represent the indirect illumination when using instant radiosity – into a small number of vi...

We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...

When initially reported [1], BTPC was compared with JPEG, GIF and research coders of that time, SPIHT and CALIC. It outperformed JPEG and GIF (except for limited-palette colour graphics) but was inferior to SPIHT and CALIC in their respective areas of strength. Tested with an assortment of images of different modalities, BTPC was the most consistent overall performer, other coders faring poorly...

F or more than two centuries, scientists and artists have come up with a range of ways to demonstrate that the wavelength composition over a whole scene can affect how we perceive the colour of the individual parts of that scene. The proportion of light of each wavelength reflected from an object can be highly beneficial in detecting or recognizing objects 1. However, to make use of that invari...

One of the complex documents in the real world is city maps. In these kinds of maps, text labels overlap by graphics with having a variety of fonts and styles in different orientations. Usually, text and graphic colour is not predefined due to various map publishers. In most city maps, text and graphic lines form a single connected component. Moreover, the common regions of text and graphic lin...
