This paper presents an agent-oriented approach to visual information retrieval. A new data model is introduced to represent image content in a top-down fashion and a deductive agent-oriented database structure is proposed to facilitate visual information representation, indexing, query, searching and maintenance. In addition, the integration of techniques in image understanding and information retrieval...
Nowadays large populations worldwide are suffering from eye diseases such as astigmatism, myopia, and hyperopia which are caused by ophthalmologically refractive errors. This paper presents an effective approach to computer aided diagnosis of such eye diseases due to ophthalmologically refractive errors. The proposed system consists of two major steps: (1) image segmentation and geometrical feature...
This paper presents a new approach to content-based image retrieval by using dynamic indexing and guided search in a hierarchical structure, and extending data mining and data warehousing techniques. The proposed algorithms include: a wavelet-based scheme for multiple image feature extraction, the extension of a conventional data warehouse and an image database to an image data warehouse for dynamic...
