Patent Images

1. A system (100) for registering a sequence of images, comprising:

  • -an input (120) for obtaining an image sequence (200) comprising a plurality of images (201) arranged sequentially within an image range and 205;

    -a transformation processor (140) for establishing a transformation between pairs of adjacent consecutive images in the sequence of images (200) to obtain a plurality of transformations (211) and

         214) as a transformation matrix;

    -an alignment processor (160) for aligning the image sequence (200) to a reference image (203) based on the plurality of transformations (211) and

         214) to obtain a registered image sequence (230);

    -wherein the alignment processor (160) is arranged for establishing the reference image (203) from the plurality of images (201) and

         205) based on a transformation metric that quantifies a degree of transformation required for aligning the sequence of images (200) to the reference image (203), wherein the alignment processor (160) is arranged for quantifying the degree of transformation based on a multiplication of the transformation matrices of adjacent pairs of consecutive images.
