Facial structure estimation device, facial structure estimation method and facial structure estimation program

摘要

Problem to be solved: to improve the estimation accuracy of the face structure based on the face image while reducing the annotation cost.The facial structure estimation device 10 includes a retrieval section 11 and a control section 13.The acquisition section 11 acquires the face image.The control section 13 functions as the identifying section 15, the estimation section 16, and the evaluation section 17.The identification unit 15 identifies the individual based on the face image.The estimation part 16 estimates the facial structure based on the face image.The evaluation unit 17 calculates the validity of the facial structure estimated by the estimation unit 16.The evaluation unit 17 applies the face structure and the face image whose validity is above the threshold value to the learning of the estimation unit 16.The control unit 13 is based on the identification result of the individual by the identification unit 15 for the application of the face structure to which the validity is above the threshold value and the estimation part 16 of the face image.Diagram
