Abstract:
A method of providing a compression of a medical image, including the steps of:providing successive wavelet transforms of the medical image, each successive wavelet transform providing quadrants respectively having representations of frequencies of LL, LH, HL and HH where the letter L represents low frequency components and the letter H represents high frequency components and where the first letter representing the frequency range in each quadrant refers to the frequency range in one of two (2) coordinate directions and the second letter in each quadrant refers to the frequency range in the other of the two (2) coordinate directions, andproviding individual compressions of the representations of the frequencies in the LH, HL and HH quadrants in the first wavelet transform and an individual compression of the representations of the frequencies in the LL quadrant in the first wavelet transform and the representations of the frequencies in the LL, LH, HL and HH quadrant in each of the successive wavelet transforms.
