1. A method for segmenting an anatomical part, comprising:
identifying a landmark on a contour/surface of a 2D/3D model of the anatomical part in an ultrasound image;
assigning a weight to the landmark;
identifying different appearance patterns of a region around the landmark based on a previously stored training set; and
applying a filter to the different appearance patterns of the region around the landmark in order to identify contours of the anatomical part.
