| Abstract | Generally, super-resolution image restoration approach is an ill-posed problem and its inversion is stabilized by regularization. It is important to set proper regularization parameter. Furthermore in many practical situations the blurring process is generally unknown or is known only to within a set of parameters, it is necessary to incorporate the blur identification into the restoration procedure. Assuming geometric warp matrixes are known, this paper presents a scheme in which regularization parameter is estimated by Signal-Noise Ratio and error-parameter analysis is combined with searching method to identify blur function during super-resolution restoration. Simulation shows that in the scheme the method of estimating regularization parameter can improve adaptive control power, make convergence of restoration algorithm better during super-resolution image restoration, and adaptively adjust this parameter when low-resolution images have different Signal-Noise Ratio; the combination of error-parameter analysis and searching method can effectively identify blur function, which reduce the cost of computation and accelerate searching speed. |
