摘要
A fast discrete wavelet encoding apparatus and method for encoding and decoding a still image are provided. In the fast discrete wavelet encoding apparatus, an energy calculator calculates the energy of an input image, block by block, each block having a predetermined number of pixels, an adaptive image decomposer determines a lifting transform level for each block adaptively according to the energy of the block, and a lifting encoder lifting encodes the input image according to the lifting transform levels determined for the blocks of the image.
