Progress in wavelet algorithms and applications

Wavelet and wavelet packet transforms are presently used for image compression and denoising. There has been recent progress on three fronts: implementing multiplication operations in wavelet bases, estimating compressibility by wavelet packet transform coding, and designing wavelet packets to control frequency spreading and pointwise convergence. Some open problems are mentioned.
