Abstract Semi-Global Matching (SGM) uses an aggregation scheme to combine costs from
multiple 1D scanline optimizations that tends to hurt its accuracy in difficult scenarios. We …

Performance evaluation of stereo or motion analysis techniques is commonly done either on
synthetic data where the ground truth can be calculated from ray-tracing principals, or on …

Multi-view matching presents significant advantages regarding accuracy, radiometric fidelity
or occlusion handling; however, the limitation of having only two available views remains …

Semi-Global Matching (SGM) is a widely-used efficient stereo matching technique. It works
well for textured scenes, but fails on untextured slanted surfaces due to its fronto-parallel …

Traditionally, subpixel interpolation in stereo-vision systems was designed for the block-
matching algorithm. During the evaluation of different interpolation strategies, a strong …

As an essential step in 3D reconstruction, stereo matching still faces unignorable problems
due to the high resolution and complex structures of remote sensing images. Especially in …

In this work we focus on creating a real-time dense stereo reconstruction system with
accurate sub-pixel estimation. We selected the Semi-Global Matching method as the basis …

GPU hardware architectures have evolved into a suitable platform for the hardware
acceleration of complex computing tasks. Stereo vision is one such task where acceleration …

Digital surface model (DSM) generation is one of the fundamental issues in photogrammetry
and the mapping industry. This paper provides a comprehensive assessment of state‐of‐the …

Dense stereo matching has been an indispensable technique for 3-D exploitation of
imagery, in which semiglobal matching (SGM) is one of the outstanding approaches and has …
