Stereo matching algorithms with different cost aggregation

Abstract

Stereo matching is one of the most active research fields in computer vision. The paper introduces the categories and the performance index of stereo matching and introduces three high-speed and state-of-the-art stereo matching algorithms with different cost aggregation: fast bilateral stereo (FBS), binary stereo matching (BSM), and a non-local cost aggregation method (NLCA). By comparing the performance in terms of both quality and speed, we concluded that FSB deals with the effects of noise well; BSM is suitable for embedded devices and has a good performance with radiometric differences; NLCA combines the efficiency with the accuracy of state-of-the-art algorithms.
