We consider the problem of data retrieval from disk storage in video server where the video data are read in constant size blocks. Retrieval algorithms of this type are referred to as Constant Data Length (CDL) retrieval algorithms We recently introduced a new retrieval algorithm called GCDL [3] that generalizes the CDL retrieval algorithm: GCDL reads for a video stream i during , , consecutive...

Relevance feedback is effective technique for bridging the semantic gap in image retrieval which diminish semantic gap between low-level visual features and high-level semantic concepts for image retrieval. Currently, crucial image retrieval system is content-based image retrieval. To improve performance of proposed content based image retrieval system, automatic relevance feedback technique is...

In this paper, Content Based Video Retrieval Systems performance is analysed and compared for three different types of feature vectors. These types of features are generated using three different algorithms; Block Truncation Coding (BTC) extended for colors, Kekre’s Fast Codebook Generation (KFCG) algorithm and Gabor filters. The feature vectors are extracted from multiple frames instead of usi...
