Retrieval Incorporating the AHP Method

In this paper, a Content-Based Image Retrieval (CBIR) system is presented. In this system, a method called the Average Area Histogram (AAH) is proposed based on the area features of the regions formed by the pixels of each color, which retains the advantages of the conventional histogram. A key issue in CBIR is to develop a proper weight assignment method for combining various image features in retrieval. The Analytic Hierarchy Process (AHP) method is imported into this system for assessing the importance of various image features. Compared with the traditional experience-based linear assignment method, our assignment is more reasonable and easy to communicate. The experimental results demonstrate the feasibility and efficiency of our proposed scheme.
