In wavelet transform encoding, high-quality encoding is to be realized by enabling picture quality control from one fractional area to another. An input picture 100 is read out in an amount corresponding to a number of lines required for wavelet transform and buffered in a memory unit 6. The input picture...http://www.google.fr/patents/US7016546?utm_source=gb-gplus-shareBrevet US7016546 - Block area wavelet transform picture encoding apparatus
