To improve image quality in computer graphics, antialiasing techniques such as supersampling and multisampling are used. We explore a family of inexpensive sampling schemes that cost as little as 1.25 samples per pixel and up to 2.0 samples per pixel. By placing sample points in the corners or on the edges of the pixels, sharing can occur between pixels, and this makes it possible to create ine...
* Fraunhofer FOKUS, Berlin, Germany + Swinburne University of Technology, Melbourne, Australia Abstract-Service Level Agreements (SLAs) specify the network Quality of Service (QoS) that providers are expected to deliver. Providers have to verify if the actual quality of the network traffic complies with the SLA. Ideally this should be done without introducing significant additional network load...
The properties of a variable area sampling technique, by which the observer varies the searchradius to obtain approximately a prescribed number of woody plants in each tier measured, were determined by (i) comparison of fixed area and variable area sampling of a computer-mapped shrub population; (ii) comparison of results from fixed area and variable area sampling of woody plants exceeding abou...
One way to sample from a distribution is to sample uniformly from the region under the plot of its density function. A Markov chain that converges to this uniform distribution can be constructed by alternating uniform sampling in the vertical direction with uniform sampling from the horizontaìslice' deened by the current vertical position. Variations on such`slice sampling' methods can easily b...
