Feature point position estimating apparatus, feature point position estimating method, and feature point position estimating program

摘要

Provided is a feature point position estimating apparatus capable of reducing the fitting of a model into a local solution and detecting facial feature points with more practical accuracy. An image input unit 11 for inputting a facial image from the outside and a face image input using a facial feature point position search parameter from templates of a plurality of facial images composed of a positive example and a negative example A nearest neighbor template calculation unit 12 for respectively obtaining a nearest neighbor template which is a template nearest to the image from the positive examples and negative examples respectively, a face feature point position search parameter A parameter gradient direction calculating unit 13 for calculating a gradient direction, and a search parameter updating unit 14 for updating the facial feature point position search parameter by adding the calculated gradient direction.
