Weighted linde-buzo-gray stippling

Fast Stippling based on Weighted Centroidal Voronoi Diagrams

Stippling is an artistic technique that has been used profusely in antiquity. One of the main problems is that it requires great skill and patience to achieve excellent results due to the large number of points that must be drawn even for small formats. The use of computers, in general, and GPUs, in particular, with their computing capacity, has allowed to overcome many of these limits. We pres...

Building a Better Racetrack

We find IIb compactifications on Calabi-Yau orientifolds in which all Kähler moduli are stabilized, along lines suggested by Kachru, Kallosh, Linde and Trivedi.

Weighted Minmax Algorithm for Color Image Quantization

The maximum intercluster distance and the maximum quantization error that are minimized by the MinMax algorithm are shown to be inappropriate error measures for color image quantization. A fast and effective (improves image quality) method for generalizing activity weighting to any histogram-based color quantization algorithm is presented. A new non-hierarchical color quantization technique cal...
