Corrected-Moment Illuminant Estimation
2013 IEEE International Conference on Computer Vision, 2013Image colors are biased by the color of the prevailing illumination. As such the color at pixel cannot always be used directly in solving vision tasks from recognition, to tracking to general scene understanding. Illuminant estimation algorithms attempt to infer the color of the light incident in a scene and then a color cast removal step discounts the

Illumination estimation for augmented reality based on a global illumination model
Multimedia Tools and Applications, 2019With the rapid development of 3D technology, the illumination consistency plays an important role in realistic rendering of virtual objects which are superimposed into the real scene. In this paper we proposed a new approach to estimate illumination, given the images of a scene.

Using the red chromaticity for illumination estimation
2015 9th International Symposium on Image and Signal Processing and Analysis (ISPA), 2015Achieving color invariance to illumination is known as color constancy and it is implemented in most digital cameras. There are statistics-based and learning-based computational color constancy methods and the latter ones are known to be more accurate.

Estimation of color under fluorescent illuminants
Proceedings of 1st International Conference on Image Processing, 2002Fluorescent lamps are the most common lighting source for desktop publishing and standard viewing conditions. In order to predict the appearance of reflective material viewed under fluorescent lamps, the CIE tristimulus values must be computed. While these values are readily computed for most smoothly varying reflectances by using a simple summation ...

Factor graphs for pixelwise illuminant estimation
2015 International Joint Conference on Neural Networks (IJCNN), 2015This paper presents a method to recover the pixel-wise illuminant colour for scenes lit by multiple lights. Here, we start from the image formation process and pose the illuminant recovery task in hand into an evidence combining setting. To do this, we construct a factor graph making use of the scale space of the input image and a set of illuminant ...

Estimation Illumination Chromaticity
2008 Second International Symposium on Intelligent Information Technology Application, 2008Color constancy is important for pattern recognition and image understanding. Based on simplified BRDF model, we use voting method to detect the high light areas. Then the pixels in the high light areas are projected to the inverse-intensity space.

Global Illumination via Density-Estimation
1995This paper presents a new method for the production of view-independent global illumi-nation solutions of complex static environments. A key innovation of this new approach is its decomposition of the problem into a loosely coupled sequence of simple modules.
