1. An apparatus for searching for feature points of an object, comprising:

  • a shape model generation unit which generates a shape model including a mean model of an object, and statistical feature data of each feature point forming a mean shape, by training a plurality of training sets in which a plurality of feature points are labeled for the object;

    an initial position resetting unit which resets an initial position of each feature point of the mean shape according to a pose of an input image; and

    a feature point extraction unit which adapts to the input image the mean shape whose initial position is reset, using the statistical feature data of each feature point of the mean shape, and extracts feature points of the input image.
