摘要
Abstract
A hlind restoration algorithm of diffusion based on anisotropic and nonlinear regularizations is proposed for restoring degraded images, in which the anisotropic and adaptive regularizations are adopted according to the character of image curvature and gradient. The nonlinear and spatial anisotropic regularization functions are suggested to smooth adaptively in the process of recovering the object image. Finally, the cost functions are minimized by alternate minimization scheme. The nonlinear equations are linear by fixed-point iteration scheme. Experiment results show that the proposed algorithm can restore image and can improve image quality effectively.关键词
