A novel nonlinear fusion filter (NFF) based on prediction and smoothing is presented. Based on the least squares fitting method of polynomial, a left prediction and right prediction operator, left smoothing and right smoothing operator, as well as center smoothing and cross valid smoothing operators are defined and given. Simulation results show that the proposed algorithm is an effective algorithm.
