FACE POSTURE ESTIMATING DEVICE, FACE POSTURE ESTIMATING METHOD, AND FACE POSTURE ESTIMATING PROGRAM

摘要

An object is to provide a face pose estimating device, a face pose estimating method, and a face pose estimating program that allow high accuracy estimation of a face pose even if a face organ cannot be detected from an image. A face organ detector 11 of the face pose estimating device 10 detects a face organ from an image frame. A face pose candidate set generator 16 generates a face pose candidate set. A first similarity estimator 12 computes 3D-model-based similarities. A second similarity estimator 13 computes appearance-based similarities. A first likelihood estimator 141 computes a first likelihood corresponding to the 3D-model-based similarity. A second likelihood estimator 142 computes a second likelihood corresponding to the appearance-based similarities. An integrated likelihood estimator 143 computes an integrated likelihood by using the first and second likelihoods. A face pose estimator 15 estimates the face pose by using the integrated likelihood.
