spelling A comparative study of grayscale conversion techniques applied to SIFT descriptorsNenhum resumo disponívelIn computer vision, gradient-based tracking is usually performed from monochromatic inputs. However, a few research studies consider the influence of the chosen color-tograyscale conversion technique. This paper evaluates the impact of these conversion algorithms on tracking and homography calculation results, both being fundamental steps of augmented reality applications. Eighteen color-to-greyscale algorithms were investigated. These observations allowed the authors to conclude that the methods can cause significant discrepancies in the overall performance. As a related finding, experiments also showed that pure color channels (R, G, B) yielded more stability and precision when compared to other approaches.Brazilian Computer Society2015-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://sol.sbc.org.br/journals/index.php/jis/article/view/66210.5753/jis.2015.662Journal of Interactive Systems; v. 6 n. 2 (2015)Journal on Interactive Systems; Vol. 6 No. 2 (2015)2763-7719reponame:Journal on Interactive Systemsinstname:Sociedade Brasileira de Computação (SBC)instacron:SBCenghttps://sol.sbc.org.br/journals/index.php/jis/article/view/662/657Macêdo, SamuelMelo, GivânioKelner, Judithinfo:eu-repo/semantics/openAccess2020-09-05T16:09:10Zoai:ojs2.sol.sbc.org.br:article/662Revistahttps://sol.sbc.org.br/journals/index.php/jis/ONGhttps://sol.sbc.org.br/journals/index.php/jis/oaijis@sbc.org.br2763-77192763-7719opendoar:2020-09-05T16:09:10Journal on Interactive Systems - Sociedade Brasileira de Computação (SBC)false
