Abstract

Flash animation as an emerging visual media spawned by the Internet, since its inception ten years time, has evolved to become the network's most popular multimedia manifestations, is widely used in education and teaching. Flash animation is a vector-based interactive video format, set all kinds of media elements, dynamic effects, user interaction in one rich semantic information by internal objects and their properties characteristic expression is the the Internet efficient delivery vector graphics, text, images, sound and video media formats play an increasingly important role in the interaction between teachers and students with the digital environment, media. How to quickly and accurately retrieve the required Flash animation from the massive network resources, give full play to the functions of Flash animation entertainment and teaching and become a new topic in multimedia research. Keyword Flash retrieval accuracy rate is not high, high based on Animation external characteristics and contextual information of the page Flash retrieval efficiency and accuracy not proceed from the structural features and visual features of Flash animation scene inside, explore the content-based Flash Animation retrieval, extraction of the Flash animated scenes features and visual features, and is part of the Flash animation content management and search engine research and development work. SWF animation files to the release of Flash animation format, SWF animation file structure and Flash production process as the basis for in-depth research, scene structure and visual features of Flash animation to achieve the segmentation of the the logical scene and the visual scene, complete expression Flash animation visual features of shape, image, and video elements feature extraction. Finally, Flash animation content feature analysis and extraction platform and content-based Flash animation retrieval system are described in detail. First, statistical analysis of the Flash animation on the network, based on Flash animation features to establish classification, each type of Flash animation content analysis and feature extraction. In accordance with the instructions of the SWF animation file format, the storage structure and operating principle of the SWF animation, Flash animation label information extraction platform, and analysis of the structural features and visual features of Flash animation scene, Flash animation content organization chart. Organizational structure based on the contents of the Flash animation Flash animation the logical scene and visual scene concept, the successful completion of a logical scene segmentation and visual scene segmentation. Nodes are defined based on the logic of the scene, the logical segmentation of the scene and save the node image; comprehensive video shot classification principles and Flash animation, visual scene features, create Flash animation visual scene classification system, provides a theoretical basis for the partition of the visual scene. Quick View Flash animation like the image thumbnail viewing, this paper, based on the concept of Flash animation summary of the scene, generate Flash animations in GIF format summary. Flash animation is a set of multiple media elements such as text, graphics, images, sound and video in one multimedia format, various media elements of movement, rotation, scaling, deformation constitutes a complex dynamic Flash animation effect, therefore, the shape , image, video objects, features and dynamic effects is a concentrated expression of Flash animation visual effects. SWF animation file format, shape, image, video object corresponding label independent SWF file storage, Flash animation label information extraction platform extract all object label information, and then extract the shape of interest to the user, image, characteristics of the video object properties, create Flash animation visual feature extraction platform. Finally, the Flash animation visual characteristic parameters written to the Flash animation content-based retrieval system feature indexing library retrieval Flash animation based on visual characteristics. This article established title Flash animation scene structure and visual features, construction the Flash animation content characteristics analysis and extraction platform for content-based Flash animation retrieval services. Flash animation scene structure analysis and visual feature extraction is the Flash animation content analysis to extract part of the platform, development tools VC 6.0, the operating environment is Windows XP. This work of Flash animation, content management and search engine research and development has brought new development has quite innovative and practical value.
