	att_abstract={{Traditional upsampling methods apply spatial-invariant filtering
across the entire image for efficiency, but often produce
unsatisfactory artifacts around the edges. We propose a novel
image upsampling algorithm that preserves the image structure,
particularly around the edges, better than previous techniques.
Our method computes a spline approximation to the
edges in the image via bitmap tracing. A scaled version of
the traced image is then used as a guide for joint bilateral upsampling
to produce the final result. Our method is easy to
implement and the visual fidelity and quality of our results
compare favorably to state-of-the-art techniques.}},
