Content-based Image Query

The objective of content-based image query is to efficiently find and retrieve images from the database that satisfy the criteria of similarity to the user's query image. When the database is large and the image features are complex the exhaustive search of the database and computation of the image similarities is not expedient. Therefore, recent techniques have been proposed to speed-up image retrieval by utilizing simple image features, such as color histograms [1], devising compact representations [2][3], efficient indexing structures [4], and utilizing effective pre-filtering techniques [5]. However, recent approaches for content-based image query have neglected one important criteria for similarity: spatial information and spatial relationships.
