We describe a novel method for propagating disparity values using directional masks and a voting scheme. The driving force of the propagation direction is image gradient, making the process anisotropic, whilst ambiguities between propagated values are resolved using a voting scheme. This kind of anisotropic densi\ufb01cation process achieves signi\ufb01cant density enhancement at a very low error cost: in some cases erroneous disparities are voted out, resulting not only in a denser but also a more accurate \ufb01nal disparity map. Due to the simplicity of the method it is suitable for embedded implementation and can also be included as part of a system-on-chip (SOC). Therefore, it can be of great interest to the sector of the machine vision community that deals with embedded and\/or real-time applications.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"986\" height=\"494\" src=\"https:\/\/jarnoralli.fi\/wp-content\/uploads\/2023\/02\/voting_mask_propagation_tsukuba_venus.png\" alt=\"\" class=\"wp-image-204\" srcset=\"https:\/\/jarnoralli.fi\/wp-content\/uploads\/2023\/02\/voting_mask_propagation_tsukuba_venus.png 986w, https:\/\/jarnoralli.fi\/wp-content\/uploads\/2023\/02\/voting_mask_propagation_tsukuba_venus-600x301.png 600w, https:\/\/jarnoralli.fi\/wp-content\/uploads\/2023\/02\/voting_mask_propagation_tsukuba_venus-300x150.png 300w, https:\/\/jarnoralli.fi\/wp-content\/uploads\/2023\/02\/voting_mask_propagation_tsukuba_venus-768x385.png 768w\" sizes=\"(max-width: 986px) 100vw, 986px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Journal of Visual Communication and Image Representation.
