Abstract :
It has been proposed to use the Discrete Wavelet Transform (DWT) in the draft MPEG-4 standard, which is expected play an important role in low bit-rate applications such as video telephony. A digital design for the DWT is presented in this paper. Related issues including the basic concept, boundary treatment, and the distributed arithmetic algorithm are addressed
