IEEE International Conference on Acoustics, Speech, and Signal Processing
作者: Solo, V Macquarie Univ Dept Stat Sydney NSW 2109 Australia
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 cruci... 详细信息
