Abstract
In accordance with an exemplary embodiment, a method is provided to generate a color look up table for multiple images. The method includes selecting color points from a first image. The first color points comprise weak image texture. The method also includes identifying feature points in a spatial neighborhood of each first color point. Additionally, the method includes identifying feature points from a second image. The second feature points correspond to the first feature points. The method also includes determining a color points in the second image. The second color points correspond to the first color points, and are determined using a spatial interpolation of the first plurality of color points from the first plurality of feature points and then applying the obtained spatial interpolation to the second plurality of feature points. Further, the method includes generating the color lookup table.
