The feature point location estimation device comprises: an image input unit which receives input of a facial image from an external source; a nearest neighbor template computation unit which obtains a nearest neighbor template from among positive examples and a nearest neighbor template from among negative examples, the nearest neighbor templates being the templates nearest to an image that is computed from the inputted facial image using a facial feature point location search parameter from among a plurality of facial image templates constituted by the positive examples and the negative examples; a parameter gradient direction computation unit which computes, from the facial feature point location search parameter and the nearest neighbor templates, a gradient direction of the facial feature point location search parameter; and a search parameter update unit which updates the facial feature point location search parameter by adding the computed gradient direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Feature point location estimation device, feature point location estimation method, and feature point location estimation program","description":"Provided is a feature point location estimation device, whereby fitting of a model is less prone to local solutions, and it is possible to detect a facial feature point with more practical precision.
