1. A method for determining if a destination profile belonging to a set of candidate destination profiles was used to transform a source image into a destination image, whereby each destination profile comprises entries defined in a source space, whereby for each entry a destination vector in a destination space is available, the method comprising: obtaining at least one destination pixel of a destination image, said pixel having a destination vector in said destination space; transforming said destination vector into an approximate destination vector in said destination space using said destination profile; calculating a distance between said destination vector and said approximate destination vector of said at least one pixel; and determining based on said distance if said destination profile was used to transform a source image into said destination image.
