Color Correction: A Novel Weighted Von Kries Model Based on Memory Colors
نویسندگان
چکیده
In this paper we present an automatic color correction framework based on memory colors. Memory colors for 3 different objects: grass, snow and sky are obtained using psychophysical experiments under different illumination levels and later modeled statistically. While supervised image segmentation method detects memory color objects, a luminance level predictor classifies images as dark, dim or bright. This information along with the best memory color model that fits to the data is used to do the color correction using a novel weighted Von Kries formula. Finally, a visual experiment is conducted to evaluate color corrected images. Experimental results suggest that the proposed weighted von Kries model is an appropriate color correction model for natural images.

Color Constancy Using Single Colors
This work investigates if the von Kries adaptation can be generalized to deal with single colored patches. We investigate which colored patches can give statistically equivalent performance to a white patch for von Kries adaptation. The investigation is then extended to couples of colors, and the analysis of the characteristics of the colors forming the couples is carried out. We focus here on ...
متن کاملUsing recovered reflectance to predict color
Predicting a surface color under different lights is an easy task if the surface reflectance function is available. However, often only colorimetric information is available, and the tristimulus values of a color that undergoes an illuminant change are estimated using transforms inspired by the von Kries coefficient rule model. We propose a new method, based on the reconstruction of multispectr...
متن کاملThe biological significance of color constancy: an agent-based model with bees foraging from flowers under varied illumination.
The perceived color of an object depends on its spectral reflectance and the spectral composition of the illuminant. Thus when the illumination changes, the light reflected from the object also varies. This would result in a different color sensation if no color constancy mechanism is put in place-that is, the ability to form consistent representation of colors across various illuminants and ba...
متن کاملNon-von-Kries 3-parameter color prediction
Chromatic adaptation transforms generally rely on a variant of the von Kries transformation method to account for changes in the LMS cone signals that occur when changing from one illuminant to another. Von Kries adaptation—also often referred to as the coefficient rule method or the diagonal transformation method—adjusts the 3 color channels by independent scale factors. Since there generally ...
متن کاملAnalysis of tristimulus interdifference and contextual color correction
We explore how an RGB representation can be computed from a spectral description of real images, with many different colors. To pass from spectral distribution to tristimulus values, several color-matching functions (CMFs) were proposed, derived from experimental setups with simplified visual conditions, considering the colors pointwise and independently from any visual context. A high interdif...
