A Non-photorealistic Rendering of Seurat's Pointillism [chapter]

Hui-Lin Yang, Chuan-Kai Yang
2006 Lecture Notes in Computer Science  
, and the effects of complementary colors and halos.  ...  To achieve simulating Seurat's painting style, we made careful observations on all accessible Seurat's paintings and extract from them some important features, such as the few primitive colors, point sizes  ...  Conclusions and Future Work We have implemented a system that could faithfully perform a non-photorealistic rendering of Seurat pointillism.  ...

Realization of Seurat's pointillism via non-photorealistic rendering

Chuan-Kai Yang, Hui-Lin Yang
2007 The Visual Computer  
Surprisingly, there was a different trend emerging in the last decade: how to perform rendering in non-photorealistic styles.  ...  [20] adopted a different approach, where they pick colors in an isoluminant manner, so that the results match well with the human perception system. Similarly, Jing et al.  ...  Her research interest is on computer graphics, with a particular focus on non-photorealistic rendering.  ...

The Role of Perception for Computer Graphics [article]

Dirk Bartz, Douglas Cunningham, Jan Fischer, Christian Wallraven
2008 Eurographics State of the Art Reports  
For rendering, this lead to the preeminence of representations based on the physics of light interacting with different media and materials.  ...  Research in virtual reality has focussed on interactivity and therefore on real-time rendering techniques that improve the immersion of users in the virtual environments.  ...  In particular in rendering, this kind of techniques are called non-photorealistic rendering, or NPR.  ...

Preserving Salience By Maintaining Perceptual Differences for Image Creation and Manipulation

Amy Ashurt Gooch
2017 unpublished
For example, although the human visual system does not have a strong absolute sense of color or intensity, images are stored as a discrete set of color or intensity values at each pixel.  ...  This dissertation examines two methods of perceptual difference preservation for two long-standing problems: 1) a color to grayscale conversion algorithm that preserves all visible color changes through  ...  Early non-photorealistic rendering techniques for computer-generated pen-and-ink illustration [51, 44] mapped illumination changes to texture or line density changes (Figure 1.9) in order to visually  ...
