     * Pixels are weighted using contrast, saturation and well-exposedness measures, than images are
     * combined using laplacian pyramids.
     *
     * The resulting image weight is constructed as weighted average of contrast, saturation and
     * well-exposedness measures.
     *
     * The resulting image doesn't require tonemapping and can be converted to 8-bit image by multiplying
     * by 255, but it's recommended to apply gamma correction and/or linear tonemapping.
     *
     * For more information see CITE: MK07 .
