Simulating hand-drawn illustration can succinctly express information in a manner that is communicative and informative. We present a framework for an interactive direct stipple rendering of volume and surface-based objects. By combining the principles of artistic and scientific illustration, we explore several feature enhancement techniques to create effective, interactive visualizations of sc...

This paper investigates the use of the Bayesian inference for devising an unsupervised sketch rendering procedure. As likelihood model of this inference, we exploit the recent statistical model of the gradient vector field distribution proposed by Destrempes et al. for contour detection. A global prior deformation model for each pencil stroke is also considered. In this Bayesian framework, the ...

bstract. We integrate stylized rendering with an efficient multiesolution image representation, enabling a user to control how ompression affects the aesthetic appearance of an image. We dopt a point-based rendering approach to progressive image transission and compression. We use a novel, adaptive farthest point ampling algorithm to represent the image at progressive levels of etail, balancing...

Research on cultural products suggest that there are substantial cultural variations between East Asian and European landscape masterpieces and contemporary members' landscape artwork (Masuda et al., 2008c), and that these cultural differences in drawing styles emerge around the age of 8 (Senzaki et al., 2014b). However, culture is not static. To explore the dynamics of historical and ontogenet...

We present a technique for painterly renderings that follows a decomposition of the canvas into a set of regions and layers (coarse to fine). The regions reflect the spatial arrangement of the composition and the order in which the painting is to be created (typically back to front), and are produced in a way that new strokes only minimally paint over existing ones. Layers reflect the applicati...

Self-portraits are more likely to show the artist's right than left cheek. This phenomenon may have a psychobiological basis: Self-portraitists often copy their subject from mirrors and, if they prefer to present their left cheek (more expressive due to right-lateralization of emotions) to the mirror, this would result in a right-cheek bias in the painting. We tested this hypothesis using Selfi...

Recent extensions to the standard difference-of-Gaussians (DoG) edge detection operator have rendered it less susceptible to noise and increased its aesthetic appeal. Despite these advances, the technical subtleties and stylistic potential of the DoG operator are often overlooked. This paper offers a detailed review of the DoG operator and its extensions, highlighting useful relationships to ot...

We present a sonification platform for generating audio driven by real-time particle collision data from the ATLAS experiment at CERN. This paper provides a description of the data-to-audio mapping interfaces supported by the project’s composition tool as well as a preliminary evaluation of the platform’s evolution to meet the aesthetic needs of vastly distinct musical styles and presentation v...

We present a novel Procedural Image Processing (PIP) method and demonstrate its applications in visualization. PIP modulates the sampling positions of a conventional image processing kernel (e.g. edge detection filter) through a procedural perturbation function. When properly designed, PIP can produce a variety of styles for edge depiction, varying on width, solidity, and pattern, etc. In addit...

I distinguish between two kinds of nostalgia in retro game design – restorative and reflective. The former manifests itself in ‘total restoration of monuments of the past’, while the latter ‘lingers in the dreams of another place and another time’. Restorative nostalgia is visible in the retrogaming practices, such as creation of emulators, appreciation of classic titles and remaking them for n...
