By using a skin-color selector, the regions with color "like" that of human skin are selected as candidates for human face. In the next stage, the candidates are matched with a face model and given an evaluation of the match degree by the matching module. And if the evaluation of the match result is too low, a reinforcement learning stage will start to search the best parameters of the skin-color selector. It has been tested using many photos of various ethnic groups under various lighting conditions, such as different light source, high light and shadow. And the experiment result proved that this algorithm is robust to the vary-ing lighting conditions and personal conditions.展开更多

The experimental result shows that this method can produce a better recognition effect than other methods in view of the problem of illumination.展开更多

In this paper, we evaluate two popular objective similarity measures by comparing them with face matching performance in human observers. The results suggest that these measures are still limited in predicting human behavior, especially in rejection behavior, but objective measure taking advantage of global and local face characteristics may improve the prediction. It is also suggested that human may set different criterions for“hit” and “rejection”and this may provide implications for biologically-inspired computational systems.展开更多

The proposed human friendly interface is implemented by a three-stage algorithm: Detection and sizing of the user's body, detection of reference points based on face detection and augmented reality markers, and superimposition of the clothing over the user's image. Compared to other existing VFR systems, key difference is the lack of any proprietary hardware components or peripherals. Proposed VFR is software based and designed to be universally compatible as long as the device has a camera. Furthermore, JAVA implementation on Android based mobile systems is computationally efficient and it can run in real-time on existing mobile devices.展开更多

In this latter sense, the human face is at the center of Emmanuel Levinas＇ theory of ethics： We encounter each other face-to-face, he argues, and it is the other＇s face that calls for my ethical response to the holiness of his/her wholeness and essence. The primary ethical imperative is： ＂Thou shalt not kill.＂ When we encounter a facially disfigured person, we usually fail to respond ethically because we concentrate on the disfigurement. The second dimension, as a result of the disfigurement, is often impaired and thus incapable of communicating in such a way that we can ＂read＂ the face. With our gaze fixed on the disfigured part of the face, we lose sight of the person as a whole. Metaphorically speaking, we could even say that we ＂kill＂ the person. Levinas conceives of the other＇s face not in its plastic manifestation. But the encounter with the other does at first take place as embodiment. According to Merleau-Ponty, this encounter is by definition interactive and dialogical. In Willa Cather＇s short story ＂The Profile,＂ young beautiful Virginia marries a portrait painter after he has finished her portrait in profile. The left side of her face is severely disfigured because of a burn. Her husband is waiting impatiently for her to talk about ＂it＂ and the suffering it must cause her in order to ＂heal＂ her with his love, but she behaves as if it did not exist and even likes to dress extravagantly. In the following analysis of the short story, it will be illustrated how the husband fails to respond to his wife＇s face＇s invitation to interact with it and get in touch with the wholeness of her person that it stands for. Instead, he reduces her to the disfigurement. When he finally names the scar, he metaphorically ＂kills＂ her, as well as their marriage.展开更多

The process of face recognition, however, is inhibited by variations in the appearance of face images caused by changes in lighting, expression, viewpoint, aging and introduction of occlusion. Although various algorithms have been presented for face recognition, face recognition is still a very challenging topic. A novel approach of real time face recognition for HCI is proposed in the paper. In view of the limits of the popular approaches to foreground segmentation, wavelet multi-scale transform based background subtraction is developed to extract foreground objects. The optimal selection of the threshold is automatically determined, which does not require any complex supervised training or manual experimental calibration. A robust real time face recognition algorithm is presented, which combines the projection matrixes without iteration and kernel Fisher discriminant analysis （KFDA） to overcome some difficulties existing in the real face recognition. Superior performance of the proposed algorithm is demonstrated by comparing with other algorithms through experiments. The proposed algorithm can also be applied to the video image sequences of natural HCI.展开更多

In this paper, a simple yet effective approach for detecting and locating human faces in color images is proposed. The contribution of this paper is twofold. First, a particular reference to face detection techniques along with a background to neural networks is given. Second, and maybe most importantly, an adaptive cubic-spline neural network is designed to be used to detect and locate human faces in uncontrolled environments. The experimental results conducted on our test set show the effectiveness of the proposed approach and it can compare favorably with other state-of-the-art approaches in the literature.展开更多

Elephants capture the affection of people but also inspire animosity and fear at the same time. This is because there are conflicts with people over space, critical resources, costs of damages and general insecurity to people. This paper examined field evidence and interviewed expert key informants on current intensity and frequency of human-elephants in Amboseli Ecosystem. According to them, generally, the most prevalent (score of 1 lowest to 10 highest) threats to elephants were competition for critical resources (6.32 ± 0.44) followed by blocking of migration (6.24 ± 0.46), harassment of elephants (4.83 ± 0.75), poaching (4.57 ± 0.37), and retaliatory killings (3.78 ± 0.31). For threats that elephants pose to people, the most prevalent one was crop raiding (6.95 ± 0.26) followed by environmental degradation (6.71 ± 0.46), general insecurity to people (5.76 ± 0.65), property destruction (5.16 ± 0.41), injury and death to livestock (3.78 ± 0.37), and injury and death to people (2.71 ± 0.27). For the severity of the threats, the highest score was given to crop raiding whose average score was 7.90 ± 0.24 followed by environmental destruction and degradation (6.89 ± 0.43), injury and death to people (6.72 ± 0.44), injury and death to livestock (6.36 ± 0.50), property destruction (5.78 ± 0.49), general insecurity to people (5.62 ± 0.64). Severity levels followed the same trend or varied slightly. These drivers of human-elephant conflicts need to be addressed decisively to protect both people and elephants. There is a need to ensure local people’s benefit from elephants through ecotourism investments such as wildlife sanctuaries, leasing critical space for elephants’ dispersal on acceptable terms, through appropriate compensation schemes for elephant costs, and supporting local community wildlife rangers to prevent conflicts.展开更多

It is particularly effective for treating disorders of the head and face. According to the meridian theory in Traditional Chinese Medicine (TCM), the Large Intestine Meridian to which it belongs originates in the hand and terminates in the face. This theory is based, however, more on thousands of years of clinical experience rather than on scientific evidence. In our study of acupuncture effects on normal human volunteers with the non-invasive BOLD (blood oxygenation level dependant)technique for FMRI (functional magnetic resonance imaging), we demonstrated widespread effects in the brain during acupuncture at Hegu and Zusanli (ST 36). A finding of special interest was observed in the primary somatosensory cortes (SI) during Hegu acupuncture. In additlon to activation of the area representing the hand in response to the sensory impulses arising from the site of stimulation, activation also occurred in the face representation in all 3 subjects brains studied by coronal brain sections. In one of these subjects activation in the face representation was even stronger than that in the hand representation. Areas representing the neck, trunk and other parts of the upper extremity also exhibited increase in signal intensity, subject to individual variability. As compared with Hegu, such effects were either absent or much weaker with acupuncture at Zusanli (ST 36) or with other forms of sensory stimulation to the hand. Functional mapping of the brain with MRI has provided the first direct evidence in support of the important role of Hegu acupuncture in TCM.展开更多

It adopts a series of continual eye movements as input to perform simple control activities. Identification of eye movements is the crucial technology in these eye-based HCI systems. At present, researches on eye movement identification mainly focus on frontal face images. In fact, acquisition of non-frontal face images is more reasonable in real applications. In this paper, we discuss the identification process of eye movements from non-frontal face images. Firstly, the original head-shoulder images of 0?–±60?azimuths are sampled without any auxiliary light source. Secondly, the non-frontal face region is detected by using the Adaboost cascade classifiers. After that, we roughly extract eye windows by the integral projection function.Then, we propose a new method to calculate the x- y coordinates of the pupil center point by searching the minimal intensity value in the eye windows. According to the trajectory of the pupil center points, different eye movements(eye moving left, right, up or down)are successfully identified. A set of experiments is presented.展开更多
