1. A method for generating a color lookup table for a plurality of images, comprising: selecting a first plurality of color points comprising weak image texture, from a first image; identifying a first plurality of feature points that lie in a spatial neighborhood of each of the first plurality of color points; identifying a second plurality of feature points from a second image, wherein the second plurality of feature points correspond to the first plurality of feature points; determining a second plurality of color points in the second image corresponding to the first plurality of color points, 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; and generating the color lookup table, including a plurality of input colors comprising the first plurality of color points, and a plurality of output colors comprising the second plurality of color points.
