This paper puts forward a new edge-directed forward and backward anisotropic diffusion model for texture enhancement and edge sharpening of image. Since forward and backward diffusion cannot hold flow-like edges, and coherence enhancement diffusion cannot sharpen edges, our new model gets a new diffusivity, which combine the merits of these two methods.

In many image resolution enhancement applications, the blurring process of the imaging system is unknown. In this paper we discuss the problem of image sharpening without estimating the point spread function (PSF). A regularization model is constructed based on the prior information of image error and image gray value, which does not need any prior of PSF.(More)
