WebLam’s automatic white balance algorithm, which combines both Gray World Assumption and Perfect Reflector Assumption algorithms. The execution steps of Lam’s algorithm were divided into three stages. The hardware-software co-design and analysis for each stage was realized.

Gray World Theory One of the simplest and the most often used assumptions about the color constancy is the so-called Gray World Theory (GWT): the majority of all visual scenes in the world can be integrated to the gray, i.e. R ...
Color correction between Gray World and White Patch
WebGrayworld assumption Assuming that we have a good distribution of colors in our scene, the average reflected color should be the color of the light. If the light source is assumed to be white, we know how much the whitepoint should be moved in the color cube.

WebA full color natural scene can also be processed in the same fashion. This “Gray World” method assumes that the world is gray and the distribution of primaries color will be equal. C. The “White Patch” method attempts to locate the objects that are truly white, within the scene; by assuming the whites pixels are also the brightest (I ... WebSep 14, 2005 · A well-known color constancy method is based on the Grey-World assumption i.e. the average reflectance of surfaces in the world is achromatic. In this article we propose a new hypothesis for color constancy, namely the Grey-Edge hypothesis assuming that the average edge difference in a scene is achromatic. Based on this … WebOct 28, 2013 · A new hypothesis for color constancy namely the gray-edge hypothesis, which assumes that the average edge difference in a scene is achromatic is proposed, and an algorithm forcolor constancy is proposed based on the derivative structure of images. 763 PDF A Large Image Database for Color Constancy Research F.
