【摘要】 在电影动画的制作过程中,经常以关键帧来代表一段动画镜头。快速,有效地抽取关键帧可以减轻多媒体数据库的负担,更重要的是,可以提高对动画镜头检索的正确率。用MPEG-7标准中的主颜色描述符对组成镜头的一系列帧进行颜色特征描述,通过计算帧间的颜色特征差异距离,可以达到有效抽取关键帧,提高检索正确率的目的。更多还原

【Abstract】 During the process of producing the cartoon movie, it often takes some key frames to express a shot scene. If we can finda way to extract the key frames fast and efficacious, it will take of the burden of the database. Furthermore, it can improve the ac-curacy of retrieving the shot scenes. Using the color descriptor of the MPEG- 7 standard to describe the series of frames that com-pose of the shot scene and calculating the different distance of the color feature, can make the aim of improving the accuracy of re-trieving the shot scenes.更多还原
