Abstract: Aiming at the problem of uniform motion blurred image,suppose the object moves along axis X. Restoration and degradation model was established based on Z- transform by strict mathematical deduction, then difference ectuation was changed into algebraic ectuation for simplifying the solving process. Because noise was easily brought and increased with image restoration processing, a fuzzy weighted mean filter was introduced into the restoration algorithm and the algorithm implementation was given concretely. Simulation results show that the proposed method could restore the uniform motion blurred image correctly,effectively and rapidly. Algorithm is not sensitive to fuzzy degree,has a certain stability and superiority compared with other algorithms.
