Abstract:

We propose a method for denoising piecewise smooth curves, given a number of noisy sample points. Using geometric variants of wavelet shrinkage methods, our algorithm preserves corners while enforcing that the smoothed arcs lie in an L2 Sobolev space Hα of order α chosen by the operator. The reconstruction is scale-invariant when using th...More
