Patent Images

1. A method of analysing a sequence of images of a deformable object in non-rigid motion, comprising:

  • detecting the boundary of the object in each image of the sequence and fitting a non-rigid contour to the detected boundary;

    tracking the boundary through the sequence by calculating a shape-space representation with respect to a first shape-space of the movement of the non-rigid contour through the sequence;

    defining a second, different shape-space whose shape vector comprises components corresponding to a desired attribute of the motion; and

    calculating from the tracked boundary the shape-vector corresponding to the different shape-space.
