<p>A method comprising forming an approximated image A(I) from an original input image I according to an approximation technique A (21), forming a pre-enhancement map (delta) by differentiating (23) the approximated image A(I) from the input image I, enhancing the pre-enhancement map (delta) according to an image enhancement technique E (25) forming an enhanced map E(delta), and combining (27) the enhanced map E(delta) with the approximated image A(I) to generate an enhanced image I'.</p> |
