ABSTRACT:
A device and method for detecting feature points of an object from an image. A three-dimensional model is created in which a plurality of nodes corresponding to feature points in a learning image are defined. The model is projected onto an input image and a feature value is derived from a plurality of sampling points around a projection point of each node. An error estimated amount is computed based on the displacement of a feature point between a correct model and an error model. The three dimensional position of each feature point in the input image is estimated based on the error estimated amount and a three dimensional model.
