Abstract
To estimate the high frequencies of a low resolution image, we propose a maximum likelihood solution whereby we incorporate a priori knowledge about the structure of the desired image. The algorithm was developed primarily for improving low resolution Magnetic Resonance spectroscopic images, where a priori structural information is obtained from anatomical features of the corresponding high resolution proton image. The algorithm involves a noniterative solution which can be easily regulated for noisy data sets.
