Claim Text:
1. A method for estimating a latent sharp image for at least a portion of a blurry image, the method comprising the steps of: estimating the latent sharp image with a control system that includes a processor (i) utilizing a first spatial mask in a fidelity term and a second spatial mask in a regularization term of a latent sharp image estimation cost function, the first spatial mask being a first array of individual weights for individual pixels in the fidelity term and the second spatial mask being a second array of individual weights for individual pixels in the regularization term, and (ii) utilizing a variable splitting technique in both the fidelity term and the regularization term during minimization of the latent sharp image function with the control system, the variable splitting technique including introducing a first auxiliary variable and a first penalty term into the fidelity term of the latent sharp image estimation cost function and introducing a second auxiliary variable and a second penalty term into the regularization term of the latent sharp image estimation cost function to split the operations of convolution and element-wise multiplication by the control system.
