Application of non-iterative method in digital image restoration

A method for digital image restoration, based on the algorithm of Lagrange multipliers, has many practical applications. We apply the method to remove blur in an image caused by uniform linear motion. This method assumes that linear motion corresponds to an integral number of pixels. Compared to other classical methods, this method attains a higher value of the Improvement in Signal to Noise Ration (ISNR) parameter and a lower value of the Mean Square Error (MSE) parameter. Moreover, this method is more time-efficient. We give an implementation in the MATLAB programming package.
