Abstract :
We present a method to find the mean square estimate of the original image using a Gauss-Markov image model and a known point spread function. The performance of the edge adaptive technique compares favorably to the Wiener filter on synthetic and real images with mild linear (motion) blur and additive white Gaussian noise
