Large multimedia databases and digital images archival systems are being created in government, military, academia, and business. Efficient methods to retrieve images from such large databases have become indispensable. In this research, we present a novel wavelet packet (WP) based method for image identification and retrieval that enables the recovery of the original image from a database even if the image has been subjected to geometric transformations. Simulation results show that our method is extremely fast and has perfect image retrieval rates from an image database of 7,500 images within 8 seconds . This method is robust and can be used for real time image retrieval.
