A Resolution-Independent Representation for Pen-and-Ink Illustrations

This paper describes a compact resolutionand scale-independent representation for penand-ink illustrations. The proposed representation consists of a low-resolution grey-scale image, augmented by a set of discontinuity segments. We also present a new reconstruction algorithm that magnifies the low-resolution image while keeping the image sharp along the discontinuities. By storing pen-and-ink illustrations in this representation, we can produce high-fidelity illustrations at any scale and resolution by generating an image of the desired size and filling that image with pen-and-ink strokes.
