Mathematical Progress in Expressive Image Synthesis IIIActive Comicing for Freehand Drawing Animation

Mathematical Progress in Expressive Image Synthesis III: Active Comicing for Freehand Drawing... [This paper presents Active Comicing, a prototype sketching system that provides enhanced frame interpolation capability for freehand drawing animation. In this system, the user draws several 2D freeform strokes interactively on multiple frames, and the system automatically constructs stroke-to-stroke interpolation frames. To compose a comprehensive and coherent least-distorting interpolation, we assume input strokeStroke matching has ghost points, which are additional points defined on stroke edges, and define affine transformations. In addition, the system semi-automatically guides the template motion of each stroke. For example, if the user draws an arrow, the system assigns the stroke moves in the direction of the arrow. To assign template motion, we compute the stroke similarity between the user’s input and stroke information from a database. With this method, it is possible to generate stroke animation on each frame without stroke interpolation. By combining these techniques, the user can generate freehand animations easily and quickly.] http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png

Abstract

[This paper presents Active Comicing, a prototype sketching system that provides enhanced frame interpolation capability for freehand drawing animation. In this system, the user draws several 2D freeform strokes interactively on multiple frames, and the system automatically constructs stroke-to-stroke interpolation frames. To compose a comprehensive and coherent least-distorting interpolation, we assume input strokeStroke matching has ghost points, which are additional points defined on stroke edges, and define affine transformations. In addition, the system semi-automatically guides the template motion of each stroke. For example, if the user draws an arrow, the system assigns the stroke moves in the direction of the arrow. To assign template motion, we compute the stroke similarity between the user’s input and stroke information from a database. With this method, it is possible to generate stroke animation on each frame without stroke interpolation. By combining these techniques, the user can generate freehand animations easily and quickly.]
