Colour transfer between images is a computer vision problem that imposes the colour characteristics of a target image onto a source image. The general characteristics of the source image do not change, with buildings, people and objects remaining generally identifiable. Uses of this technique include but are not limited to, automatic colouring a grayscale image, altering of the mood of a particular scene, or colour matching an image to fit in a set. This report explores 2 different colour transfer algorithms, an algorithmic, statistical approach and another approach utilizing N-Dimensional Probability Density Function (PDF) Transfer to transfer characteristics across images.
