A New Spatial Hue Angle Metric for Perceptual Image Difference
Color image difference metrics have been proposed to find differences between an original image and a modified version of it. One of these metrics is the hue angle algorithm proposed by Hong and Luo in 2002. This metric does not take into account the spatial properties of the human visual system, and could therefore miscalculate the difference between an original image and a modified version of...
متن کاملRod influence on hue-scaling functions
Rod influence on hue appearance of spectral lights was characterized by comparing the scaling of red, green, yellow, and blue hue sensations for an 8 degrees-diameter, 7 degrees-eccentric test spot under conditions that minimized (cone plateau) and maximized (dark adapted) rod influence at two mesopic light levels (1.5 and 3.0 log scoptic trolands). At the lower light level, the hue-scaling fun...
متن کاملColor constancy and hue scaling.
In this study, we used a hue scaling technique to examine human color constancy performance in simulated three-dimensional scenes. These scenes contained objects of various shapes and materials and a matte test patch at the center of the scene. Hue scaling settings were made for test patches under five different illuminations. Results show that subjects had nearly stable hue scalings for a give...
متن کاملA New Angle on Angle Surgery
G laucoma surgery has long relied on ab externo techniques such as augmented trabeculectomy and tube-shunt procedures. While these have excellent potential to lower intraocular pressure (IOP), they are associated with risks, including hypotony, and are therefore conventionally reserved for those with advanced glaucoma or at high risk of visual loss. Traditional filtering surgery attempts to byp...
