Multimedia content analysis and search

摘要

After 15 years of extensive research, multimedia retrieval has finally come to its prime time when everything becomes accessible on the web. However, web search provides both a new paradigm and poses a new challenge to the multimedia retrieval research community. It calls for a rethinking of the traditional content-based approaches, especially in how to make use of the massive yet noisy meta data associated with the web pages and links. In this talk, we will first review some familiar approaches in content-based multimedia retrieval. Then, we will present a set of efforts in web multimedia search to illustrate interesting new thoughts that potentially will lead to new breakthroughs in multimedia search and stimulate new research ideas.
