In this study, the performance of the sequential summed area … WebThe Summed Area Table(SAT) is a transformation of some rectangular data set (like an image) such that every entry in the table equals the value of its corresponding source entry, plus all entries below and to the left of it. Thus, the values are constantly increasing from the bottom-left corner to the top-right corner.
