Abstract

Recently, calculation speed of computers has become faster and capacity of archival media has become larger. These situations enable image databases which efficiently archive, retrieve and utilize large amounts of image data. In order to retrieve required images efficiently from large amounts of image data, it is necessary to extract effective keywords from original images automatically. Many methods have been proposed for this purpose. However, satisfactory methods have not been found yet. In this paper, a new image data management method using vector expression of hue distribution of color images is proposed. A kind of normalized histogram of hue of a color image is regarded as a vector which represents image features. This unit vector of hue is utilized as a basis of the keywords of the image. The proposed image data management method enables flexible interface for various requests on retrieval. For example, `navigation in image data space based on similarity,' `retrieval of partial images or similarity retrieval using partial images,' `retrieval by semantic description,' such as `mountain view with clear sky and green forest' can be realized using the proposed method. The results of simulation experiments reveal the effectiveness of the proposed method.
