We present RenderAnts, the first system that enables interactive Reyes rendering on GPUs. Taking RenderMan scenes and shaders as input, our system first compiles RenderMan shaders to GPU shaders. Then all stages of the basic Reyes pipeline, including bounding/splitting, dicing, shading, sampling, compositing and filtering, are executed on GPUs using(More)

Recent years, various information theoretic based measurements have been proposed to remove redundant features from high-dimensional data set as many as possible. However, most traditional Information-theoretic based selectors will ignore some features which have strong discriminatory power as a group but are weak as individuals. To cope with this problem,(More)
We introduce a vector representation called <i>diffusion curve textures</i> for mapping diffusion curve images (DCI) onto arbitrary surfaces. In contrast to the original <i>implicit</i> representation of DCIs [Orzan et al. 2008], where determining a single texture value requires iterative computation of the entire DCI via the Poisson equation, diffusion(More)
Metabolome analysis including amino acid profile is under investigation as an approach in cancer screening. The present study aims to analyze plasma free amino acid (PFAA) profiles in cancer patients and investigate their potential as biomarkers of malignancy. Plasma samples from 56 gastric cancer patients, 28 breast cancer patients, 33 thyroid cancer(More)
Diffusion curve primitives are a compact and powerful representation for vector images. While several vector image <i>authoring</i> tools leverage these representations, automatically and accurately vectorizing <i>arbitrary</i> raster images using diffusion curves remains a difficult problem. We automatically generate sparse diffusion curve vectorizations(More)
