Kullback-Liebler Measure Applied to the Blind Deconvolution
HU Bi-jin · Mathematica Applicata · 2006
In the inversion of the seismic,to solve the problem of a blind deconvolution is pretty difficult.There are various methods to discuss this problem,such as the method of the cumulant moments etc.In the paper,the problem of a blind deconvolution in the seismic is discussed by the functional method,by which Likas etc study the problem on the restoration of an image.A statistical function (i.e.the variational function),the maximum point of which includes the information of the reflective coefficient sequence,is obtained by using the Kullback-Liebler information measure,and the algorithm is devised for computing the maximum value of the variational function.
