Multiscale curvatures for identifying channel locations from DEMs
We developed a method called Hyperscale Channel Extraction (HCE). HCE identifies channel locations in a digital elevation model. HCE explicitly uses information at multiple scales simultaneously. HCE can distinguish noise and likely channelized regions. HCE counteracts the effect of blurring due to isotropic wavelet filtering.
