HU Bi-jin · Journal of Chongqing Jiaotong University · 2006
In the inversion of the seismic,solving the problem on a blind deconvolution is pretty difficult.There are various methods to discuss this problem,such as the method of the cumulant moments etc.In this paper,the problem on a blind deconvolution in the seismic is discussed by using the functional method,by which Likas et al studied the problem on the restoration of an image.A statistical function(i.e.the variational function),the maximum point of which includes the wavelet and the coefficient sequence of the reflections,is obtained by using the Kullback-Liebler information measure,and the algorithm is devised for computing the the maximum value of the variational function.
