1. A computer-implemented method for estimating the movement of an image position of an image feature between a first image and a second image, the method comprising:
determining a set of image windows in the first image, each image window having the image feature,
identifying at least a portion of the set of image windows in the second image,
for the portion of the set of image windows, evaluating the quality of an assignment of each image window in the first image to the given image window in the second image, and selecting one of the image windows on the basis of the evaluation, and
estimating the movement of the image position of the image feature using the selected image window,
wherein the set of image windows comprises an initial image window, and the method comprises a detection of an edge in the initial image window, wherein the determination of the image windows contained in addition to the initial image window in the set of image windows takes place on the basis of the detected edge.
