Abstract
The present invention is related to a image compression and transmission method, and particularly to a method of relocating a wavelet packet coefficient for a zerotree coding in order to optimize an encoder to be suitable for transmitting image off-line. To realizing the present invention, for the wavelet packet coefficients, located on frequency bands which are divided in several subbands according to frequency of an image data thereon, the present invention collects coefficients in same location on each of the subbands, and relocates the collected coefficients in a same location in an integrated frequency band, formed by integrating the subbands.
