Subband Coding of Signals
Murilo Bresciani De Carvalho, Eduardo A. B. da Silva · IGI Global eBooks · 2002
In this chapter we deal with subband coding of signals. We begin with an introduction to rate-distortion theory, and after that we discuss subband compression schemes in general. We then describe popular still image and video coding algorithms using subband decompositions, including DCT and wavelet-based methods. R-D optimization-based techniques such as wavelet packets are also described. We finish the chapter with a brief account of subband-based audio compression schemes.
