Diffusion Mosaic

Large textures that can provide realistic details are widely used in modeling, gaming, art design, etc. Texture synthesis is a way to create large textures based on a small sample pattern, which can be obtained by image examples or hand­drawn work by an artist. Different methods that aim to achieve better visual effects on reducing or avoiding...

Hardware accelerated ray tracing for diffusion curves

This paper accelerates the rendering of diffusion curves using the ray tracing cores found on modern NVIDIA graphics cards using the method described by Bowers et al. [Bowers, Leahey and Wang 2011]. This method approximates the final result of the Poisson equation and in this paper is accelerated using Optix and dedicated ray tracing hardware....

Depth Map Design and Depth-based Effects With a Single Image

We present a novel pipeline to generate a depth map from a single image that can be used as input for a variety of artistic depth-based effects. In such a context, the depth maps do not have to be perfect, but are rather designed with respect to wanted result. Consequently, our solution centers around user interaction and relies on a scribble...

Depth and Motion Information for 2D Image Sequences

Diffusion curves as defined by Orzan et al. (2008) have so far been only applied to single, static images. We propose a system to construct diffusion curves over a sequence of images. These curves can then be used to construct depth and motion information to augment the image sequence.
