The feature transformation apparatus includes a section that acquires respective prescribed activity data of one or more reference individuals and a subject when the one or more reference individuals and the subject perform a prescribed activity. A section extracts a reference individual feature of the one or more reference individuals and a subject feature of the subject. A calculation section calculates at least one standard feature based on the one or more reference individual features. A transform matrix between the standard feature and the subject feature is calculated. Recognition object activity data is acquired when the subject performs a recognition object activity. A recognition object feature of the subject is extracted from the recognition object activity data. The recognition object feature is transformed using the transform matrix."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Feature transformation apparatus and feature transformation method","description":"A feature transformation apparatus recognizes activities of subjects in adaptation to each individual and improves recognition accuracy.
