Content-based image retrieval, which provides convenient ways to retrieve images from large image databases, has been studied actively. While many previous image retrieval techniques do not look at regions in an image, regionbased image retrieval techniques have been gaining attention recently. We propose a region-based image retrieval method which performs image segmentation and indexing using texture features computed from wavelet coefficients. The proposed method has advantages in texture feature extraction and hierarchical image segmentation over the previous region-based techniques using wavelet transform.
