Abstract :
In this paper, hypotenuse information detection and judgment is added based on the combination of vertical information and horizontal information of image edge and the improved hybrid filter algorithm is proposed. Simulation results show that compared with other algorithms such as median, Wiener filter and hybrid filter algorithm ,the improved hybrid filter algorithm proposed by this paper can better restrain noise and keep the information of image edge.
