Hierarchical diffusion curves for accurate automatic image vectorization
2014
ACM Transactions on Graphics
Links: DL PDF Previous approaches use edge detection to place curves along sharp image features, relying on the assumption that regions with high Laplacian magnitude will overlap intensity discontinuities in the image domain. We show that, although this assumption is valid for sharp edges, it does not hold in general. Specifically, for blurred edges or bumps, the image edges do not overlap the Laplacian maxima (e.g, Fig. 3 ). We observe this behavior in both natural images and computer
