Abstract
A method for determining a movement of a device relative to at least one object based a digital image sequence of the object recorded from the location of the device. The method includes computing a plurality of optical flow fields from image pairs of the digital image sequence; finding the position of an object in a partial image region in the most current image in each case and assigning the partial image region to the object; forming a plurality of partial optical flow fields from the plurality of optical flow fields; selecting a partial flow fields from the plurality of partial flow fields in accordance with at least one criterion to facilitate the estimation of a change in scale of the object; and estimating the change in scale for the at least one object using the assigned partial image region based on the selected partial flow field.
