ABSTRACT:
Index keys from JPEG encoded still images are extracted based on the gray-scale, luminance, and/or chrominance values. The index keys are stored in a database, along with corresponding location, and size information. The index key of a query image, also encoded in the JPEG format, is extracted. The index key of the image query is compared with the index keys stored in the meta database, with still images having index keys similar to the index key of the query image identified. The still images are then retrieved and displayed by selection of a user.
