Controllable Diffusion Curves

Abstract : This report introduces new drawing tools for controlling color diffusion in an image. It builds on the Diffusion-Curve algorithm, which computes images by diffusing colors from user-defined constraint curves. However, control of the diffusion process was limited in significant ways. In this report, we adapt the representation of Diffusion Curves by allowing artists to specify color strength, diffusion directions, and non-diffusing barriers. We also describe the algorithmic changes necessary for their efficient implementation. We demonstrate how these extensions give artists more control, and streamline the editing process in common situations.
