- There is a surge of activity in Wavelet Theory/Analysis. Some of the work
- there verges on deliberately "fuzzifying" signal and image representations in
- the Wavelet domain (for purposes of signal/image compression). A preprint,
- "Ideal Spatial Adaptation by Wavelet Shrinkage" by David L. Donoho and Iain M.
- Johnstone, Dept. of Statistics, Stanford, is available for FTP access.
- (playfair.stanford.edu)
-
- The abstract begins:
-
- With ideal spatial adaptation, an oracle furnishes information about how best
- to adapt a spatially variable estimator - piecewise constant, piecewise
- polynomial, variable knot spline, or variable bandwidth kernel - to the unknown
- function. ...
-
- In my humble opinion (no theorems allowed!), this area of work "looks"
- (fuzzily) a lot like a fuzzy "spectrum".
-
- As an aside:
-
- Yes, I was involved in "fuzzy sound", collaborating with a composer (Ralph
- Cherubini) on composition in the Walsh-Hadamard + Time domain. Our work "Small
- Changes" was presented at the (2nd?) Computer Music Conference in Urbana.
