Abstract:
A method for generating an objective function for a deformable model of a shape boundary, comprising:dividing the model of the shape boundary into a plurality of sectors;selecting, for each one of the plurality of sectors of the model of the shape boundary, a continuous model of feature value density for at least one feature of the boundary;applying corresponding sectors of a plurality of training images to the plurality of sectors of the model of the shape boundary, each one of the corresponding sectors of the plurality of training images representing ground truth of corresponding sectors of the shape boundary;obtaining, from each of the corresponding sectors of the plurality of training images and for each of the sectors of the model of the shape boundary corresponding thereto, a feature value for at least one preselected feature, resulting in a respective distribution of feature values for each of the sectors of the model of the shape boundary;deriving, for each of the sectors of the model of the shape boundary, a distribution function from the continuous model and the respective plurality of feature values; andusing the derived distribution functions in generating a sector dependent objective function.
