Abstract
In one embodiment, an image containing a number of colors is received. The image is divided into a number of sections, and an importance value is determined for each section. For each section of the image, a frequency of each color is determined. For each color in the image, a weighted score is calculated based on the frequency of that color in a particular section, and the importance value in the particular section. The weighted scores are used to adjust an error metric used to determine an approximation function for a color profile to transform the image from a first color space to a second color space, where the error metric measures the difference between the approximation function and an ideal function curve for the transformation.
