On the basis of gray edge hypothesis, further considering the influence of image edge
information and high frequency noise on light color estimation, a color constancy calculation …

Aiming at the problem of low illumination image color estimation, a method based on white-
grey-black block supervision is proposed. The standard swatch is placed in a low …

Illuminant color estimation in an image under multiple illuminations is proposed. In the most
conventional methods, the image is divided into small regions and estimated the local …

The purpose of color constancy algorithm is to eliminate the influence of illumination on the
color of objects in the scene, so that the computer has the same color constancy ability as …

An improvement in the existing weighted grey-edge (GE) framework for colour constancy is
proposed. The acquired images are denoised by vector filtering and then, a two-step colour …

Illumination estimation is most important step in color constancy computation. Although a
number of elaborate algorithms were proposed, methods like grey world and Max_RGB are …

Color constancy is used to determine the actual surface color of the scene affected by
illumination so that the captured image is more in line with the characteristics of human …

Color constancy is a phenomenon of perceiving the same color regardless of a scene
illuminant. In the computational world, this is achieved by estimating the illuminant …

White balance (WB) is the correction process to remove unrealistic color casts caused by an
illuminant color. For high-quality image correction, it is important to accurately estimate the …

In the process of remote sensing image restoration, color correction is very important. The
polynomial algorithm color correction method based on standard color card is the most …
