OPTIMUM LINEAR FILTERING FOR LINE SCAN IMAGING SYSTEMS
Abstract
A new model for the analysis of a class of line scan imaging systems which permits the quantitative comparison of the performance of one- d t o-dimensional linear filtering operations is developed. In this model the electro-optical components involved in the actual recording of a continuous two-dimensional spatial signal are characterized as a single pre-filter. The scanning process is characterized as a one-dimensional sampling of the continuous two-dimensional signal at the output of the pre-filter. Thus, the actual recorded data con ists of sets of parallel lines which are available for either one or two-dimensional processing in a postfilter. Using this conceptual model, the analytical problems reduces to de ermining the optimum one or two-dimensional post-filters in terms of known input signal and pre-filter descriptions. (Author)
