摘要： An autofocusing system in which optimal or nearly optimal linear filters are selected for filtering an image signal so that the components of the image signal which contain image content, and thus, focus information are amplified while the components of the image signal which contain noise are damped. One set of nearly optimal linear filters are modified second order difference filters in which the number of internal zeros are modified to tune the filter to the particular equipment.

摘要： An image registration (alignment) system which achieves alignment by determining an optimal focus for a composite image produced from the combination of misregistered images. The system also uses optimal or nearly optimal linear filters for filtering the combined image to emphasize (enhance) alignment information in the combined image and to de-emphasize (damp) noise. One set of the nearly optimal linear filters are modified second order difference filters in which the number of internal zeros are modified to tune the filter to the particular equipment.
