Abstract We introduce the prediction filtering method in f-x-y domain.The prediction filtering method using singular value decomposition in f-x-y domain has been put forward in this paper.The f-x-y prediction filtering can be applied after the SVD filtering.Thus the prediction filtering is carried out in f-x-y domain.Finally we compare the routine prediction filtering method with the prediction filtering method using singular value decomposition.The theoretical modeling results show that the method can more effectively increase the signal/noise ratio than the routine method.And it can maintain the continuity of effective events.
