Abstract
In one embodiment, an image is received by a computing device, the image corresponding to a first color space. A color profile is created for transforming the image from the first color space to a second color space, the creation of the color profile being based on an approximation function for transforming the image. The approximation function is determined by a polyline which comprises a number of line segments. The polyline is separated from an ideal function curve for transforming the image by an error value that is within a pre-determined threshold.
