摘要：In this paper, a forward and backward (FB) fourth order PDEs is presented to denosing and enhancement image simultaneously. The new FB fourth order PDEs preserves the advantage of YK model and avoids leaving isolated black and white speckles. Moreover, the new model preserves fine details, sharp corners, curved structures and thin lines. Experiment results show the effectiveness of the proposed model and demonstrate its superiority to the existing models.
