Wavelet packet image coding using space-frequency quantization · Computer Science, Engineering. IEEE Transactions on Image Processing · 1998.

We extend our previous work on space-frequency quantization (SFQ) for image coding from wavelet transforms to the more general wavelet packet transforms.

Since the Space-frequency tree pruning algorithm presented next produces a wavelet packet representation over seperate spatial segments we can apply the coder ...

Abstract—This paper addresses progressive wavelet image coding within the trellis-coded space-frequency quantization. (TCSFQ) framework [1].
