Today, people rely almost full time on digital texts. It is not surprising that handwriting earned a special status, and solutions to mimic real handwriting became attractive. A particular field called handwriting synthesis generates renderings of te

Superpixels are fundamental in many visual computing applications, and most existing algorithms are designed to work with pinhole-based images. However, immersive applications are gaining visibility with the growing number of devices for capturing an

Many graphics and also non-graphics applications need efficient techniques to find the nearest neighbors of a given query point. There are two approaches to address this problem: space-partitioning and data-partitioning. We present a data-partitionin

Image morphing has been extensively studied in computer graphics and it can be summarized as follows: given two input images, morphing algorithms produce a sequence of inbetween images which transforms the source image into the target image in a visu

We present a two-dimensional model for tumor growth and morphology. The model contemplates, among other biological processes, cellular adhesion and the rigidity of the tissue embedding a tumor. We find that for some values of adhesion and rigidity, t
