A new study has corrected the work of Erwin Schrödinger after an error was found in the famed physicist’s 3D math. The new discovery has the potential to create more vibrant monitors and screens, as well as printed materials and textiles.
Modeling human color perception enables automation of image processing, computer graphics, and visualization tasks.
However, the team was not expecting to discover that the longstanding application of Riemannian geometry, which allows generalizing straight lines to curved surfaces, didn’t work. Bujack and her colleagues discovered that Riemannian geometry overestimates the perception of large color differences. This is because people perceive a big difference in color to be less than the sum you would get if you added up small differences in color that lie between two widely separated shades. And Riemannian geometry cannot account for this effect.
