Folding avoidance in skeletal strokes

Skeletal strokes is a method for mapping vector artwork defined along a straight path onto an arbitrary destination path. It is commonly used to give sketches a hand-drawn look, by mapping a scanned natural-medium stroke onto a user-drawn path. When the destination path turns corners or has areas with a small radius of curvature, the mapped artwork takes on an undesirable folded or creased appearance inside the corner or curve. We present a method to eliminate the folds in many cases by adjusting the skeleton before using it to map the artwork. While this cannot address all cases with folding, it gives greatly improved results in the cases that it can address.
