For the purpose of efficiently and effectively retrieving the desired images from a large image database, the development of a user-friendly image retrieval system is indispensable. In this paper, we propose a contentbased image retrieval method based on the discrete wavelet transform (DWT) that is possessed of the superiority in multiresolution analysis and spatial-frequency localization. Further, to bridge the gap between the retrieving results and the users' expectation, we developed an interactive user interface such that the users can adjust the weights for each wavelet feature according to their expectations. Then, the system will retrieve the images that are most satisfied to the users' need from the image database via the selected multiresolution wavelet features of interest. We have performed experiments on a database with 1000 images and the results show the effectiveness of our approach.
