Improved minimum entropy deconvolution

Since its introduction, the Minimum Entropy Deconvolution method has received much attention from Geophysicists because of its ability to compensate for the actual phase of the wavelet. In practice, the method has not proven to be reliable in many cases because of .the inherent ambiguity of the solution, and has been replaced by more robust but rough parametric methods.  In this work, a technique for resolving ambiguities is proposed and applied. The technique essentially consists in using parametric methods as a coarse estimate for the proper initialization of the MED algorithm. Furthermore, adaptive and superresolutive features are added to the method. Results on both simulated and recorded traces are presented.
