交互式快速动画制作需要丰富的动画素材库作为支撑,因此,有必要研究动画素材的标注与检索技术,为动画素材的重用提供支持.研究并实现了交互式快速动画制作素材标注与检索系统,首先建立丰富的动画素材库,然后研究动画场景和形象等素材的语义标注方法,最后在此基础上实现对动画素材的颜色分块特征、局部不变特征、形状等多种特征的浏览与检索.系统具有良好的可扩展性、交互性以及快速检索能力,其关键技术已在动画制作企业得到实际应用,并取得了良好的应用效果.
Interactive fast cartoon making is based on the abundant cartoon material database. Thus it is necessary to study the annotation and retrieval of cartoon material so as to reuse the cartoon material. This paper studies and realizes a cartoon material annotation and retrieval system for interactive fast cartoon making. First, it builds a database with abundant cartoon material. Then, it studies the semantic annotation methods of cartoon scene and feature material. Finally, it proposes various browsing and retrieval methods based on the feature of color, invariant local feature and shape, etc. The system is proved to be extensible, interactive and has the ability of fast retrieval. Some of its key techniques have already been applied successfully in cartoon making enterprises.
