In this paper, the Radio-frequency identification (RFID) technology and face recognition are integrated for access control system. A rapid face detection scheme which using a set of rotated haar-like features is adopted for face detection. A normalization process is then applied to adjust the detected faces. The speeded up robust features (SURF) algorithm is used for registering the detected face...
This paper presents a cost-sensitive ordinal hyperplanes ranking algorithm for human age estimation based on face images. The proposed approach exploits relative-order information among the age labels for rank prediction. In our approach, the age rank is obtained by aggregating a series of binary classification results, where cost sensitivities among the labels are introduced to improve the aggregating...
Face recognition is a very important topic in the field of pattern recognition. Traditional two-dimensional face recognition technologies using images taken by a single camera are easily influenced by expressions and poses resulting in low recognition accuracy. In this paper, a new three-dimensional face recognition technique is proposed. We apply a dual camera module to extract two images of simulated...
Face identification is the problem of determining whether two face images depict the same person or not. This is difficult due to variations in scale, pose, lighting, background, expression, hairstyle, and glasses. Thus, a powerful feature descriptor with local-deformation tolerance ability and discriminating capability is essential to fulfill all these variations. In this paper, we present a local...
Recently medical cosmetology has attracted significant business opportunity. Micro cosmetic surgery usually involves the minimally invasive cosmetic procedures such as non-ablative laser procedure for skin rejuvenation. However, an appropriate treatment selection for skin relies on accurate preoperative evaluation. In this paper, an automatic facial skin defects detection and recognition system is...
Skin analysis is one of the most important procedures before medical cosmetology. Most conventional skin analysis systems are semi-automatic. They often require human intervention. In this study, an automatic facial skin defect detection approach is proposed. The system first detects human face in the facial image. Based on the detected face, facial features are extracted to locate regions of interest...
Issues of friendly human-machine interfaces have driven various researches, such as face animation, face recognition, and facial expression recognition in the last decade. The success of these applications relies on the accuracy of the detected facial features. Despite that facial features may be extracted automatically by some methods, however, the effective results were obtained in certain restricted...
In our daily life, it is much easier to distinguish which person is elder between two persons than how old a person is. When inferring a person's age, we may compare his or her face with many people whose ages are known, resulting in a series of comparative results, and then we conjecture the age based on the comparisons. This process involves numerous pairwise preferences information obtained by...
Facial expression recognition is one of the most popular topics in emotion analysis. Most facial expression recognition systems are implemented by general expression models. Since facial expressions may be expressed differently by different people, inaccurate results are unavoidable. The proposed facial expression recognition system recognizes facial expressions using facial features of the individual...
An emotion recognition system with consideration of facial expression and physiological signals is proposed in this paper. A specific designed mood induction experiment is performed to collect facial expressing images and physiological signals of subjects. We detected 14 feature points and extracted 12 facial features from facial expression images. Meanwhile, we measure the skin conductivity, finger...
In general, the principal component analysis (PCA) technique is applied to reduce the feature dimensions. In this paper, different from traditional PCAs, the PCA is used to select adequate centers for the classifier of radial basis function neural networks (RBFNN). In addition, a novel weights updating method is also included in the RBFNN for face recognition. The specific design, not only increases...
