Abstract
We consider total variation denoising in the presence of coloured noise. We show that noise can sometimes but not always cause major problems with reconstruction. We suggest that signal to noise ratio is not the crucial factor, rather the spectral content of the noise is crucial. We show how to modify the reconstruction algorithm to deal with coloured noise as well as how to do automatic tuning parameter selection
