Spatio-temporal edge focusing

Abstract

An automated edge detection algorithm, referred to as spatio-temporal edge focusing, is presented. It combines spatial edge focusing and temporal edge focusing. While spatial edge focusing and temporal edge focusing each have their own advantages and disadvantages, it is shown that the combination of these two techniques maintains their advantages while minimizing or removing most of their disadvantages. The final result is an automated edge detection algorithm that produces relatively noise-free edge maps with well-localized edges.<>
