Description: some fast feature extraction algorithms are addressed for joint retrieval of images
compressed in JPEG and JPEG2000 formats. In order to avoid full decoding, three fast algorithms that
convert block-based discrete cosine transform (BDCT) into wavelet transform are developed, so that
wavelet-based features can be extracted from JPEG images as in JPEG2000 images.
