Semantic White Balance: Semantic Color Constancy Using Convolutional Neural Network

Œe goal of the computational color constancy is to preserve the perceptive colors of objects under di‚erent lighting conditions by removing the e‚ect of color casts occurred by the scene’s illumination. With the rapid development of deep learning based techniques, signi€cant progress has beenmade in image semantic segmentation. In this work, we exploit the semantic information together with the...

Color quantization using modified median cut

We describe some observations on the practical implementation of the median cut color quantization algorithm, suitably modified for accurate color rendering. The RGB color space is successively divided in such a way that colors with visual significance, even if relatively small in population, are given representatives in the colormap. Appropriately modified, median cut quantization is nearly as...

Shape from Color Consistency Using Node Cut

In this paper, we present a method to estimate the shape of a three dimensional (3D) object by enforcing color consistency in the views of object points in images acquired from different viewpoints. The estimated shape and color information of the object can be used to render new views of the object. We first construct a 3D voxel space and assign to each voxel a photo inconsistency value, and t...

The color of water: using underwater photography to estimatewater quality

We describe a model for underwater illumination that is based on how light is absorbed and scattered by water, phytoplankton and other organic and inorganic matter in the water. To test the model, we built a color rig using a commercial point-and-shoot camera in an underwater housing and a calibrated color target. We used the measured spectral reflectance of the calibration color target and the...
