A spatially adaptive gradient-projection image restoration

In this letter, we propose a spatially adaptive image restoration algorithm. using local statistics, The local variance, mean and maximum value are utilized to constrain the solution space, These parameters are computed at each iteration step using partially restored image, A parameter defined by the user determines the degree of local smoothness imposed on the solution, The resulting iterative algorithm exhibits increased convergence speed when compared with the non-adaptive algorithm. In addition, a smooth solution with a controlled degree of smoothness is obtained. Experimental results demonstrate the cap ability of the proposed algorithm.
