Color Eigenflows: Statistical Modeling of Joint Color Changes
We develop a linear model of commonly observed joint color changes in images due to variation in lighting and certain non-geometric camera parameters. This is done by observing how all of the colors are mapped between two images of the same scene under various “real-world” lighting changes. We represent each instance of such a joint color mapping as a 3-D vector field in RGB color space. We sho...
متن کاملColor Constancy from Illumination Changes
Elimination of illumination color in color images is essential for various fields in computer vision. Many methods have been proposed to solve it, however there are few methods employing varying illumination as a constraint. We found Finlayson et al. ’s method [10] applicable for natural images, and extended it by making the reference illumination variable. To evaluate our method, we have condu...
متن کاملColor and COD removal from waste water containing acrylic water base color using Fenton's oxidation process
Degradation of acrylic water base color from synthetic wastewater by the Fenton process was performed. Experiments were conducted on the sample containing 100 and 400 mg/l of Acrylic water base color. The study was performed for searching optimum values of FeSO4 and H2O2 concentration, pH and temperature. The H2O2 requirement seems to be re...
متن کاملA Study of Relationship Between Color Inconstancy Level and CIELAB Color Coordinates
In commercial point of view, it is of great interest to find colors with high color constancy level. Color constancy as a relatively property of object’s appearance could be affected by different factors. In this article, the color inconstancy index of CMCCON02 and CIELAB color coordinate of 1269 samples of Munsell at CIELchº color system to study any correlations, was calculated. The correspon...
