Patent

CA 2328037

The invention relates to an image encoding/decoding method, apparatus thereof and a recording medium in which a program therefor is recorded, whereby the encoding/decoding can be obtained with high image quality at high speed. In an image encoding method which comprises producing a DC image composed of each block mean value by dividing an image data per B pixel into a block, making a part of said DC image a DC nest, and where the differential vector <dj> which is obtained by separating the DC value DCJ from the pixel block <Rj> to be encoded is over an allowable value Z, calculating one or more orthogonal basis (.alpha.k <Vk>), to which the differential vector is approximated, by the adaptive orthogonal transform (AOT) using the DC nest, each of the lowest n (n = log2 B) bits of base extraction blocks <Ui> which are down-sampled from the DC nest is set to 0. Further, base extraction vectors <ui>are produced by separating a block mean value ai from the base extraction blocks <Ui>.
