System for displacement vector searching during digital image analysis

摘要

In a system for displacement vector searching in digital image analysis, sub-totals of the amount differences in gray value for the pixel data of two images are calculated in parallel for more than one pair of pixels. These sub-totals are subsequently added together in an accumulator unit. In a control computer connected to the accumulator unit, the displacement vector is determined by selecting the minimum of a number of such added values.
