Scale-Dependent Reproduction of Pen-and-Ink Illustrations
This paper describes a representation for pen-and-ink illustrations that allows the creation of high-fidelity illustrations at any scale or resolution. We represent a pen-and-ink illustration as a low-resolution grey-scale image, augmented by a set of discontinuity segments, along with a stroke texture. To render an illustration at a particular scale, we first rescale the grey-scale image to the desired size and then hatch the resulting image with pen-and-ink strokes. The main technical contribution of the paper is a new reconstruction algorithm that magnifies the low-resolution image while keeping the resulting image sharp along discontinuities. CR Categories and Subject Descriptors: I.3.3 [Computer Graphics]: Picture/Image Generation -- Display algorithms; I.3.6 [Computer Graphics]: Methodology and Techniques -- Device independence; I.4.3 [Image Processing]: Enhancement -- Filtering. Additional Key Words: discontinuity edges, image magnification, image resampling, non-photorealistic...
