Existing real-time automatic video abstraction systems rely on local contrast only for identifying perceptually important information and abstract imagery by reducing contrast in low-contrast regions while artificially increasing contrast in higher contrast regions. These methods, however, may fail to accentuate an object against its background for the(More)
The success of using streamline technique for visualizing a vector field usually depends largely on the choice of adequate seed points. Turk and Banks developed an elegant technique for automatically placing seed points to achieve a uniform distribution of streamlines on a 2D vector field. Their method uses an energy function calculated from the low-pass(More)
This paper presents a novel feature-aware rendering system that automatically abstracts videos and images with the goal of improving the effectiveness of imagery for visual communication tasks. We integrate the bilateral grid to simplify regions of low contrast, which is faster than the separable approximation to the bilateral filter, and use a feature(More)
Eyesight and speech are two channels that humans naturally use to communicate with each other. However both the eye tracking and the speech recognition technique available today are still far from perfect. Our goal is find how to effectively make use of these error-prone information from both modes, in order to use one mode to correct errors of another(More)
We present AtelierM++, a new interactive marbling image rendering system which allows artists to create marbling textures with real-time visual feedback on mega-pixel sized images. Marbling is a method of aqueous surface design, which can produce patterns similar to marble or other stone, hence the name. The system is based on the physical model of the(More)
This paper proposes an extension to the existing automatic pencil drawing generation technique based on line integral convolution (LIC). The original LIC pencil filter utilizes image segmentation and texture direction detection techniques for defining outlines and stroke directions, and the quality of a resulting image depends largely on the result of image(More)
This paper presents a new technique for automatically converting digital images into colored pencil drawings. In real colored pencil drawing, artists use different colors for different regions, and add pure colors directly onto paper to build the target color through optical blending. To support such effect, our technique extends the existing technique for(More)
