DCT transform domain, using a formula for enhanced image quality. Is that in the case of keeping the same image, to shift more of the energy to high-frequency sound, looks more clearly stated. To fast for compression in the transmission process to enhance the images, DCT-domain image enhancement technology, it has become very urgent. DCT-domain image enhancement technique can eliminate the inverse transform to space and transform back into the computation of the DCT domain.
