Introduction to Special Issue on Represenatation and Retrieval of Visual Media in MultiMedia Systems (2)
This is the second issue of the special issue of Multimedia Tools and Applications, devoted to Representation and Retrieval of Visual Media in Multimedia System, with the emphasis on implemented prototypes, tools and applications. This issue includes three papers focus-ing on video content analysis and representation. The first paper by Lee, Li, and Xiong presents an experimental video information management system. It describes briefly the video parsing subsystem for extracting low-level visual features of video data, and gives a detailed description on the conceptual clustering scheme implemented in the system for video content representation. The paper by Ardizzone and La Cascia reports a video in-dexing and retrieval system that supports automatic video structure parsing, shot feature extraction and content-based retrieval. Experimental results are discussed in detail. The last paper by Nack and Parkes presents a case study of the applications of a video semantics and theme representation scheme in automated editing and generation of humorous video from stock material. It addresses the problem of video editing modeling to realize a thematic specification by knowledge representation approaches, a very first step towards intelligent video editing.
