Fast features for face authentication under illumination direction changes
In this letter we propose a facial feature extraction technique which utilizes polynomial coefficients derived from 2D Discrete Cosine Transform (DCT) coefficients obtained from horizontally and vertically neighbouring blocks. Face authentication results on the VidTIMIT database suggest that the proposed feature set is superior (in terms of robustness to illumination changes and discrimination ...
متن کاملGradient Edge Map Features for Frontal Face Recognition under Extreme Illumination Changes
The aim of this work is to match images of frontal faces across extreme illumination changes. This is a problem of importance in a broad range of practical scenarios. For example, the user is commonly asked to face the camera in security applications which perform authentication before granting access to a resource. Retrieval systems also often focus on nearly frontal faces because face detecti...
متن کاملFace authentication with undercontrolled pose and illumination
Though face recognition gained significant attention and credibility in the last decade, quite few commercial applications are presently able to actually benefit from this. As a matter of fact, the high intra-class variability, mainly due to changes in pose and lighting, strongly hinders a wider diffusion of this biometry in real-world applications. In this paper, we propose FACE (Face Analysis...
متن کاملFace Recognition under Varying Illumination
This paper proposes a novel pipeline to develop a Face Recognition System robust to illumination variation. We consider the case when only one single image per person is available during the training phase. In order to utilize the superiority of Linear Discriminant Analysis (LDA) over Principal Component Analysis (PCA) in regard to variable illumination, a number of new images illuminated from ...
متن کاملFace Recognition: the Problem of Compensating for Changes in Illumination Direction
A face recognition system must recognize a face from a novel image despite the variations between images of the same face. A common approach to overcoming image variations because of changes in the illumination conditions is to use image representations that are relatively insensitive to these variations. Examples of such representations are edge maps, image intensity derivatives, and images co...
