Color2Gray: salience-preserving color removal
TLDR
The Color2Gray algorithm is a 3-step process: 1) convert RGB inputs to a perceptually uniform CIE L*a*b* color space, 2) use chrominance and luminance differences to create grayscale target differences between nearby image pixels, and 3) solve an optimization problem designed to selectively modulate thegrayscale representation as a function of the chroma variation of the source image.

Non-photorealistic rendering
TLDR
The ubiquity of computer-generated imagery around us, in movies, advertising or on the Internet is already being taken for granted and what impresses most people is the photorealistic quality of the images. Expand

Does the Quality of the Computer Graphics Matter when Judging Distances in Visually Immersive Environments?
TLDR
In the real world, people are quite accurate in judging distances to locations in the environment, at least for targets resting on the ground plane and distances out to 20 m. Expand

The Influence of Restricted Viewing Conditions on Egocentric Distance Perception: Implications for Real and Virtual Indoor Environments
We carried out three experiments to examine the influence of field of view and binocular viewing restrictions on absolute distance perception in real-world indoor environments. Few of the classicalExpand

A non-photorealistic lighting model for automatic technical illustration
TLDR
We present a non-photorealistic lighting model that allows shading to occur only in mid-tones so that edge lines and highlights remain visually prominent. Expand

Interactive technical illustration
TLDR
A rendering is an abstraction that favors, preserves, or even emphasizes some qualities while sacrificing, suppressing, or omitting other characteristics that are not the focus of attention. Expand

The Lit Sphere: A Model for Capturing NPR Shading from Art
TLDR
This paper presents algorithms for mapping shading from works of art to geometric models, allowing the user to interactively explore novel viewpoints of 3D models based on the style of a reference art work. Expand

Effects of Stereo Viewing Conditions on Distance Perception in Virtual Environments
TLDR
We manipulate stereo viewing conditions in a head mounted display and show the effects of using both measured and fixed inter-pupilary distances, as well as bi-ocular and monocular viewing of graphics, on absolute distance judgments. Expand
