1. A method of registering a first image and a second image, the method comprising:

  • identifying (S1) one or more significant features within said first image;

    placing (S2) at least one control point at a significant feature within said first image, determining (S7) a first parameter setting defining a position and displacement parameters in respect of said at least one control point so as to elastically deform (S8) said first image and thereby to improve the similarity between said first image and said second image, and repeating the steps of;

    placing (S6) at least one additional control point within said first image, determining (S7) a second parameter setting in respect of said at least one additional control point and defining a position and displacement parameters so as to elastically deform (S8) said first image and thereby to further improve said similarity between said first image and said second image until a predetermined criterion is met.
