Multimedia Indexing and Retrieval: Recent research work and their challenges

The need for Multimedia Indexing and Retrieval (MIR) is rising because of huge amount of videos are producing day by day. This requires techniques for indexing and retrieving multimedia information. This paper surveys the multimedia indexing and retrieval techniques. In order to perform video indexing and retrieval video annotation is required in which keyframe extraction plays a major role. So, a new algorithm based on divide and conquer strategy is proposed for keyframe extraction. Based on the motion activity of the events in the shot/scene, the shot is declared as static or dynamic, According to the native of shot, it can be further divided into subshots and so on. The proposed algorithm reduces redundancy in keyframes and suitable for diverse content of video.
