1. A method for tracking a data object in a plurality of consecutive images by evaluating a first image and a sequential second image comprising the steps: a) constructing from the first image a template candidate region containing a landmark image feature; b) for the template candidate region, deriving by a processor from the first image an optimally sized template by minimizing an entropy of a predictive probability distribution of a warp estimate that is a function of a template size, image data of the first image, and a prior probability distribution over a plurality of warp parameters; d) identifying a second landmark in the second image by template matching using an estimated warp parameter; e) assigning the second image as the first image and assigning a third image sequential to the second image as the second image; and g) repeating steps a) to e) until the plurality of consecutive images has been evaluated.
