Antialiasing algorithm for focal plane arrays

Abstract

The use of focal plane arrays introduces an aliasing problem which transfers higher spatial frequencies onto lower frequency regions and restricts the available spatial resolution or field of view. An anti-aliasing interpolation algorithm has been developed to improve this spatial resolution. The image is initially expanded to the required size with a usable lower frequency region which contains the aliased higher frequency components. A maximum likelihood criterion is then applied to estimate this higher frequency information based on a statistical image model, so that the aliasing effect can be reduced.
