Claim One:
1. An apparatus comprising: a unit configured to acquire an object shape regression model having an average object shape, a plurality of regression functions and a plurality of feature selection maps, from a plurality of training samples; a unit configured to set an initial object shape for an object image based on the average object shape; a unit configured to calculate at least one feature vector with respect to a plurality of feature points of the initial object shape; a unit configured, for each coordinate of the plurality of feature points, to select feature fragments from the calculated feature vector based on a corresponding one of the plurality of feature selection maps and assemble the feature fragments into a sub feature vector; and a unit configured, for at least one coordinate of at least one feature point, to predict a coordinate increment based on the corresponding sub feature vector and a corresponding one of the plurality of regression functions.
