Patent ID: 7376249

Claim:
A method for determining a movement of an imaging of a background in a sequence of images of a scene, which method comprises the steps of storing position-dependent image information coming from images from a part of the sequence; selecting a correspondence between a first and second area from, respectively, an input image from the sequence and the image information, on the ground of agreement of an image content in the areas involved; determining the movement from locations of the first and second area in, respectively, the input image and the image information, characterized in that the method comprises the steps of composing a combination image with pixels built up through combination of several images of the sequence; determining a change image which indicates position-dependently to what extent there are differences between the image content of pixels from the sequence of images contributing to the same pixel in the combination image; wherein selecting the correspondence is carried out depending on the change image, such that a probability that a candidate area is selected as second area in the correspondence is made less according as the change image indicates that the changeability of pixels in that candidate area is greater.
