The procedures of Donoho, Johnstone‚ Kerkyacharian and Picard [DJKP] estimate functions by inverting thresholded wavelet transform coefiicients of the data. The Choice of threshold is crucial to the success of the rnethod and is currently subject to an intense research effort. We describe how we have applied the statistical techniqtle of cross-validation to choose a threshold and we presexlt results that indicate that its performance for correlated data. Finally, to illustrate the tech- niques, we apply various wavelet-based estimation methods to some noisy one- and two-dimensional Signals and display the results.
