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 estimation section 16.The estimation part 16 estimates the facial structure based on the face image.The control section 13 tracks the start feature points constituting the face structure by a predetermined tracking algorithm in the face image of the frame after the frame of the face image using the estimation of the facial structure.The control section 13 tracks the tracking feature points with the predetermined algorithm in the face image of the original frame to obtain the result feature points.The control section 13 selects the face image whose interval between the result feature points and the starting feature points is a threshold meeting for learning.The control section 13 learns the face image obtained by selecting the estimation section for learning and the face structure estimated by the estimation section 16 based on the face image.Diagram
