FLCFE: A Novel Method for Extracting Content Features of Flash

With the advancement and development of the Internet, Flash has penetrated into all aspects of people´s lives. As a popular multimedia, Flash has the advantages of strong artistic expressions, simple manufacture, flexible interaction and small storage, so Flash is widely used on the Internet. Currently, the shortages of researches about extracting content features of Flash seriously impose restrictions on the retrieval and utilization of Flash. Therefore, this paper proposes a novel method called FLCFE which is used for extracting content structure features from Flash. The method can effectively extract the content features of Flash, such as metadata information and component elements. On the basis of optimizing the efficiency of FLCFE, we build an experimental prototype of FLCFE through C++. Several simulation experiments based on three parameters, the Precision Ratio, the Recall Ratio and the Time Consumption, have been carried out respectively. Results show that FLCFE not only has good performances of the Recall Ratio and the Precision Ratio, but also has stable performance of time efficiency.
