A method for colorizing a monochrome image is provided. The method includes the step of transforming the monochrome image to a luminance color domain and also transforming a color sample corresponding to the monochrome image to the luminance color domain. The method also includes the step of mapping the transformed color sample on to the transformed monochrome image and merging the transformed color sample with a lightness channel of the transformed monochrome image to yield a final image. A further step of the method involves transforming the final image to a color space.
