基于场景的Flash动画摘要研究及其教育应用

Research on Scene ─ Based Flash Animation Summarization and Education Application

Flash是一种重要的多媒体形式，在教学中应用十分广泛，通过分析Flash动画的内部结构，提取关键帧图象，采用区域颜色差加权综合算法进行关键帧聚类，生成基于场景的Flash动画摘要，实现Flash动画的快速浏览，有利于准确检索、更好地使用Flash教学资源。

Flash is an important multimedia type， and used in education widely. According to the analysis of Flash’s internal structure， the authors extract the key frame images；then use the weighted integration of blocks color distance algorithm to measure key frames visual similarity for clustering；finally complete the scene─based Flash animation summarization. The research on scene─based Flash animation summarization is helpful for Flash quick browsing， accurate retrieval， and great use of Flash instructional resources.
