We present an approach for accelerating hierarchical radiosity by clustering objects. Previous approaches constructed effective hierarchies by subdividing surfaces, but could not ...
Much recent work in computational morphology has presupposed that morphological operations are de nable on strings of phonological or graphemic objects. By contrast, theoretical l...
Accurate and precise estimation of the noise variance is often of key importance as an input parameter for posterior image processing tasks. In MR images, background data is well s...
The automatic detection of runway hazards from a moving platform under poor visibility conditions is a multifaceted problem. The general approach that we use relies on looking at ...
Large Virtual Worlds (VWs) are increasingly common in the computer graphics areas of simulation, games, geospatial or scientific visualisation. In such VWs, simulated motion of th...
