摘要: A novel method is proposed in this paper to restore document images. The based on finding the degree of similarity between tested pixel and its neighbors different door's sizes. If every door size has enough with at least two pixels, then deemed original pixel. number pixels chosen, make sure that a part an text or series similar pixels. Simulation results indicate new delivers superior performance rapidly efficiently either terms noise removal details preservation.
