mv number: Effective Key to Represent Images

Recent research has given more importance on the optimization of the indexing structure; however there is a great need for research in the area of image representation for efficient retrieval. In this paper we present a method for reducing dimensions in multi-dimensional multimedia data while preserving similarities between different images. We propose to reduce the multi-dimensionality of the feature vectors to a single unique key called the mv number. Using this mv number as an effective key to represent image, we could achieve better efficiency in image matching and retrieval.
