IMAGE-RESTORATION WITH NOISE SUPPRESSION USING THE WAVELET TRANSFORM

This paper shows how an effective noise suppression strategy can be in corporated into image restoration algorithms. The widely-used Richards on-Lucy method is used here. The residual in the fit of the restored i mage, at each iteration, is analysed using a wavelet transform. In ord er to suppress noise, significant wavelet coefficients, only, are reta ined. The effectiveness of this procedure is illustrated with a range of examples. Limitations of this approach, and pointers to work in pro gress, are also outlined.
