1. A method of tracking an object comprising the steps of: (i) obtaining a plurality of images of a target object; (ii) calculating a super-resolved image of the target object from the plurality of images; (iii) obtaining a further image of the target object; and (iv) correlating the further image with the super-resolved image, in order to identify the location of the target object in the further image, whereby the, higher quality, super-resolved image may thus be used in order to better identify the location of the target object in the, lower quality, further image.
