Abstract: The motion blur generated by the relative motion during the object and the imaging system is one of the most common reasons for image degradation, in order to obtain good restoration results, a novel motion blur image restoration algorithm is proposed based on cepstrum and fast total variation de-convolution in this paper. The motion blur parameters（blur orientation and length）of point spread function are estimated based on the cepstrum method, and then the motion blur image is restored by fast total variation de-convolution method, the simulation experiments are carried out to test the performance of algorithm on many images. The results show that, compared with classical image restoration algorithms, the proposed algorithm can obtain better restoration affects, and has a certain practical reference value.
