The recent success of the Kinect sensor has a significant impact on 3D data based computer applications. This study aims to obtain MPEG-4 compliant realistic and animatable face models from Kinect video. The complete framework for this process includes initially the computation of high quality 3D scans from RGB-D Kinect video, and then the computation of animatable MPEG-4 face models using these high...
Recent studies show that the performances of face recognition systems degrade in presence of makeup on face. In this paper, a facial makeup detector is proposed to further reduce the impact of makeup in face recognition. The performance of the proposed technique is tested using three publicly available facial makeup databases. The proposed technique extracts a feature vector that captures the shape...
The recent success of emerging RGB-D cameras such as the Kinect sensor depicts a broad prospect of 3-D data-based computer applications. However, due to the lack of a standard testing database, it is difficult to evaluate how the face recognition technology can benefit from this up-to-date imaging sensor. In order to establish the connection between the Kinect and face recognition research, in this...
Face photographs, videos or masks can be used to spoof face recognition systems. Recent studies show that face recognition systems are vulnerable to these attacks. In this paper, a countermeasure technique, which analyzes the reflectance characteristics of masks and real faces, is proposed to detect mask attacks. There are limited studies on countermeasures against mask attacks. The reason for this...
There are several types of spoofing attacks to face recognition systems such as photograph, video or mask attacks. Recent studies show that face recognition systems are vulnerable to these attacks. In this paper, a countermeasure technique is proposed to protect face recognition systems against mask attacks. To the best of our knowledge, this is the first time a countermeasure is proposed to detect...
Face recognition that is robust to alterations applied on face via plastic surgery or prosthetic make-up can be still considered as a new topic. In this paper, a block based face analysis approach is proposed which provides a fairly good recognition performance together with the advantage of robustness to such kind of alterations. For this study, a simulated nose alteration face database is used which...
