Pose Normalization Using Generic 3D Face Model as a Priori for Pose-Insensitive Face Recognition
نویسندگان
چکیده
Abrupt performance degradation caused by face pose variations has been one of the bottlenecks for practical face recognition applications. This paper presents a practical pose normalization technique by using a generic 3D face model as a priori. The 3D face model greatly facilitates the setup of the correspondence between non-frontal and frontal face images, which can be exploited as a priori to transform a non-frontal face image, with known pose but very sparse correspondence with the generic face model, into a frontal one by warping techniques. Our experiments have shown that the proposed method can greatly improve the recognition performance of the current face recognition methods without pose normalization.

3D Face Recognition using Patch Geodesic Derivative Pattern
In this paper, a novel Patch Geodesic Derivative Pattern (PGDP) describing the texture map of a face through its shape data is proposed. Geodesic adjusted textures are encoded into derivative patterns for similarity measurement between two 3D images with different pose and expression variations. An extensive experimental investigation is conducted using the publicly available Bosphorus and BU-3...
متن کاملD View - Invariant Face Recognition Using a Hierarchical Pose - Normalization Strategy
Face recognition from 3D shape data has been proposed as a method of biometric identification as a way of either supplementing or reinforcing a 2D approach. This paper presents a 3D face recognition system capable of recognizing the identity of an individual from a 3D facial scan in any pose across the view-sphere, by suitably comparing it with a set of models (all in frontal pose) stored in a ...
متن کامل3D Generic Elastic Models for 2D Pose Synthesis and Face Recognition
Pose, illumination, expression and the generalization of such effects to unseen face data samples are the fundamental problems faced in face recognition. The significant contribution of this thesis is the ability to match any two face images with a large pose angle variation. This approach utilizes a proposed 3D prior face model in order to cover a wide range of poses. To achieve this, a rapid ...
متن کاملRobust face recognition using 2D and 3D data: Pose and illumination compensation
The paper addresses the problem of face recognition under varying pose and illumination. Robustness to appearance variations is achieved not only by using a combination of a 2D color and a 3D image of the face, but mainly by using face geometry information to cope with pose and illumination variations that inhibit the performance of 2D face recognition. A face normalization approach is proposed...
متن کاملPose-invariant face recognition using a 3D deformable model
The paper proposes a novel, pose-invariant face recognition system based on a deformable, generic 3D face model, that is a composite of: (1) an edge model, (2) a color region model and (3) a wireframe model for jointly describing the shape and important features of the face. The 4rst two submodels are used for image analysis and the third mainly for face synthesis. In order to match the model t...
