The success of graphics systems that render photorealistic output has obscured parallel
developments in nonphotorealistic rendering. A review of these" expressive" systems …

Recent advent of graph signal processing (GSP) has spurred intensive studies of signals
that live naturally on irregular data kernels described by graphs (eg, social networks …

Humans perceive the three-dimensional structure of the world with apparent ease. However,
despite all of the recent advances in computer vision research, the dream of having a …

This paper describes a new framework for processing images by example, called" image
analogies." based on scanned real-world examples; and texture-by-numbers, in which …

Recent extensions to the standard Difference-of-Gaussians (DoG) edge detection operator
have rendered it less susceptible to noise and increased its aesthetic appeal for stylistic …

We present a new method for creating an image with a handpainted appearance from a
photograph, and a new approach to designing styles of illustration. We “paint” an image with …

In this paper, we describe a non-photorealistic rendering system that conveys shape using
lines. We go beyond contours and creases by developing a new type of line to draw: the …

We present an automatic, real-time video and image abstraction framework that abstracts
imagery by modifying the contrast of visually important features, namely luminance and color …

This paper describes the various artistic effects of watercolor and shows how they can be
simulated automatically. Our watercolor model is based on an ordered set of translucent …

Good information design depends on clarifying the meaningful structure in an image. We
describe a computational approach to stylizing and abstracting photographs that explicitly …
