Robust Head Pose Estimation Using a 3D Morphable Model

الملخص EN

Head pose estimation from single 2D images has been considered as an important and challenging research task in computer vision.

This paper presents a novel head pose estimation method which utilizes the shape model of the Basel face model and five fiducial points in faces.

It adjusts shape deformation according to Laplace distribution to afford the shape variation across different persons.

A new matching method based on PSO (particle swarm optimization) algorithm is applied both to reduce the time cost of shape reconstruction and to achieve higher accuracy than traditional optimization methods.

In order to objectively evaluate accuracy, we proposed a new way to compute the pose estimation errors.

Experiments on the BFM-synthetic database, the BU-3DFE database, the CUbiC FacePix database, the CMU PIE face database, and the CAS-PEAL-R1 database show that the proposed method is robust, accurate, and computationally efficient.
