Content Based Video Retrieval Systems

摘要

With the development of multimedia data types and available bandwidth there is huge demand of videoretrieval systems, as users shift from text based retrieval systems to content based retrieval systems.Selection of extracted features play an important role in content based video retrieval regardless of videoattributes being under consideration. These features are intended for selecting, indexing and rankingaccording to their potential interest to the user. Good features selection also allows the time and spacecosts of the retrieval process to be reduced. This survey reviews the interesting features that can beextracted from video data for indexing and retrieval along with similarity measurement methods. We alsoidentify present research issues in area of content based video retrieval systems.
