MOTIVATION: Extract features (contours, lines, junctions) from arbitrary images at multiple scales. Applied to image manipulation, sketch reconstruction, color filtering, etc.
INSPIRATION: The Scale-Space litterature and use of Gaussian Derivatives. Adelson et al work on steerable filters and image pyramids. Zucker et al. work on folds and flows.
