Abstract

One of the generic image/signal processing problems is how to restore accurately the first order point singularity feature having the discontinuity of the first derivative that is furthermore masked with nosy clutter environment. This is known as the class of ill-condition inverse problem in a real world environment. Specifically, given the noisy sensor data, how to reconstruct the unknown singularity as the feature of the unknown source/object. We consider the rooftop singularity for the noisy sensor inverse problem, and demonstrate that the multiresolution paradigm-wavelet transform is useful to restore the source/object singularity.
