We present a new approach for performing high-quality edge-preserving filtering of images
and videos in real time. Our solution is based on a transform that defines an isometry …

The Hough transform (HT) is a popular tool for line detection due to its robustness to noise
and missing data. However, the computational cost associated to its voting scheme has …

Image matting aims at extracting foreground elements from an image by means of color and
opacity (alpha) estimation. While a lot of progress has been made in recent years on …

We present an extension to texture mapping that supports the representation of 3-D surface
details and view motion parallax. The results are correct for viewpoints that are static or …

This paper presents a technique for mapping relief textures onto arbitrary polygonal models
in real time. In this approach, the mapping of the relief data is done in tangent space. As a …

We present a technique for performing high-dimensional filtering of images and videos in
real time. Our approach produces high-quality results and accelerates filtering by computing …

Montmorillonite modified with a quaternary ammonium salt C30B/starch nanocomposite (C30B/ST-NC),
silver nanoparticles/starch nanocomposite (Ag-NPs/ST-NC) and both silver …

The goal of visualization is to effectively and accurately communicate data. Visualization
research has often overlooked the errors and uncertainty which accompany the scientific …

We introduce a physiologically-based model for pupil light reflex (PLR) and an image-based
model for iridal pattern deformation. Our PLR model expresses the pupil diameter as a …

Several cellular mechanisms affect nuclear morphology which can therefore be used to
assess certain processes. Here, we present an analytic tool to quantify the number of cells in a …
