It implies the presence of some \u201climit of color \/ luminance extent\u201d in a natural scene; if color or luminance of an object exceeds the limit, it will appear to \u201cglow.\u201d Then, what determines the \u201climit?\u201d In this project, we will investigate the limitations of color and luminance contrast in natural images and its neural basis by using psychophysics, functional brain imaging technique, and computational models.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1200\" height=\"567\" src=\"https:\/\/shitsukan.jp\/deep\/en\/wordpress\/wp-content\/uploads\/2023\/09\/D02-2_Figure_E-Ichiro-Kuriki-1200x567.png\" alt=\"\" class=\"wp-image-423\" srcset=\"https:\/\/shitsukan.jp\/deep\/en\/wordpress\/wp-content\/uploads\/2023\/09\/D02-2_Figure_E-Ichiro-Kuriki-1200x567.png 1200w, https:\/\/shitsukan.jp\/deep\/en\/wordpress\/wp-content\/uploads\/2023\/09\/D02-2_Figure_E-Ichiro-Kuriki-600x283.png 600w, https:\/\/shitsukan.jp\/deep\/en\/wordpress\/wp-content\/uploads\/2023\/09\/D02-2_Figure_E-Ichiro-Kuriki-768x363.png 768w, https:\/\/shitsukan.jp\/deep\/en\/wordpress\/wp-content\/uploads\/2023\/09\/D02-2_Figure_E-Ichiro-Kuriki-1536x725.png 1536w, https:\/\/shitsukan.jp\/deep\/en\/wordpress\/wp-content\/uploads\/2023\/09\/D02-2_Figure_E-Ichiro-Kuriki-2048x967.png 2048w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Colorization to a black-and-white image yields or increases \u201creality\u201d of the subject.
