A Hybrid Boundary Element and Boundary Integral Equation Method for Accurate Diffusion Curves

Seungbae Bang, Kirill Serkh, Oded Stein, Alec Jacobson

Abstract: In theory, diffusion curves promise complex color gradations for infinite-resolution vector graphics. In practice, existing realizations suffer from poor scaling, discretization artifacts, or insufficient support for rich boundary conditions. In this paper, we utilize the boundary integral equation method to accurately and efficiently solve the underlying partial differential equation.
