“…[7][8][9] GW hypothesis suggests that a color image is composed of three color components -R, G, and B; and the ratio of these components should tend to the same. This method estimates the illuminant using average color of the pixels and assumes that the average reflectance in a scene is achromatic.…”

Color constancy is an important problem in machine vision and image processing fields. We propose a new method in this paper that is based on detail information description to estimate the chromaticity of the light source and restore the real color property of captured images. The main idea of the proposed approach is that according to human vision characteristics use the interest information in an image to estimate the lighting condition of real scene.To approve the proposed method, two well-known algorithms are selected and their contrast results are also presented. It is shown in this paper that the proposed approach performs better than other traditional methods for color constancy most of the time.

“…According to traditional methods, for a 24-bit RGB image, AWB needs to estimate scene color temperature and calculate chromatic aberration parameters. The Gary-world assumption and Perfect reflect theory are the most prevalent algorithms [6,7]. However, these assumptions involve a series of hypothesizes which are difficult to keep consistent with real scene.…”

Automatic white balance algorithm (AWB) is significant for color temperature restoration of digital imaging system. According to the limitations and disadvantages of existing traditional white balance methods, in this paper a new AWB algorithm for airborne camera is proposed. Using RGB and histogram information divide the input image into different color character regions; according to the color richness level, adopt different white balance algorithms to achieve chromatic aberration adjustment. Experiment results show the effectiveness of the proposed AWB algorithm for airborne camera.
