N2 - In this research, we propose a flexible subblock image retrieval scheme which is robust to object translation, lighting change, object appearance or disappearance in an image which is divided into 9 non-overlapping subblocks. Furthermore, using Ohta-color moments and biorthogonal wavelet frames from each subblock, we can reduce the dimension of color space and improve the retrieval performance. Also, as two features are applied to the multi-step k-nearest neighbor algorithm, this system clearly outperforms the global color histogram intersection, RGB moments, and HSI moments using the same method.
