โœฆ Synopsis

A spatial domain technique for restoring out-+focus images, with a minimum a priori knowlealge about the Point-Spread Function (PSF) of the imaging system, is presented.

In the proposed algorithm an estimate of the spatial constant (a) of the Gaussian PSF is obtained, which is then utilized to calculate in a least-squares sense a corresponding 2-D recursive (IIR) digital,filter transfer function. This filter is then used to restore the blurred image. This procedure is applied to d$erent blurred images, and the results obtained demonstrate the eflectiveness of the method.

A methodology is introduced for rapid reduced-order solution of stochastic partial differential equations. On the random domain, a generalized polynomial chaos expansion (GPCE) is used to generate a reduced subspace. GPCE involves expansion of the random variable as a linear combination of basis fun
