Abstract

A method which improves the signal-to-noise ratio in derived images is discussed. It is shown that if the derived images are filtered appropriately it may be possible to improve the signal-to-noise ratio considerably. The advantage of the current method over low-pass filtering is that one may be able to retain some of the high spatial frequency detail in the processed images. The method is applied to the mapping of molecular diffusion constant by NMIR imaging. 1.
