Publication number: 20190147613Abstract: Techniques are provided for estimation of human orientation and facial pose, in images that include depth information. A methodology embodying the techniques includes detecting a human in an image generated by a depth camera and estimating an orientation category associated with the detected human. The estimation is based on application of a random forest classifier, with leaf node template matching, to the image. The orientation category defines a range of angular offsets relative to an angle corresponding to the human facing the depth camera. The method also includes performing a three dimensional (3D) facial pose estimation of the detected human, based on detected facial landmarks, in response to a determination that the estimated orientation category includes the angle corresponding to the human facing the depth camera.Type: ApplicationFiled: June 2, 2016Publication date: May 16, 2019Applicant: INTEL CORPORATIONInventors: HAIBING REN, YIMIN ZHANG, XIAOBO HU, FEI DUAN
