Recognition of human faces using a gallery of still or video images and a probe set of videos is systematically investigated using a probabilistic framework. In still-tovideo recognition, where the gallery consists of still images, a time series state space model is proposed to fuse temporal information in a probe video, which simultaneously characterizes the kinematics and identity using a mot...

Predation by wolves affects all livestock farming systems, including those having different batches of animals being simultaneously grazed in distinct and sometimes distant fenced pastures scattered over a landscape. In the absence responsible human herding watching his flock or herd, protection sole combination fences guard dogs is new practice France, that has not yet received much attention ...

Visual communication plays an important role in human communication and interaction. In order to interact socially, we must be able to process faces in a variety of ways. In this paper, an algorithm for invariant recognition of human faces based on LVQ neural network is presented. The proposed system is shown to exhibit robustness in achieving better classification results with both good genera...

This paper investigates the impact of contradictory emotional content on people’s ability to identify the emotion expressed on avatar faces as compared to human faces. Participants saw emotional faces (human or avatar) coupled with emotional texts. The face and text could either display the same or different emotions. Participants were asked to identify the emotion on the face and in the text. ...

We investigated event-related brain potentials elicited by repetitions of cars, ape faces, and upright and inverted human faces. A face-selective N250r response to repetitions emerged over right temporal regions, consistent with a source in the fusiform gyrus. N250r was largest for human faces, clear for ape faces, non-significant for inverted faces, and completely absent for cars. Our results ...

Whether non-human animals can recognize human signals, including emotions, has both scientific and applied importance, and is particularly relevant for domesticated species. This study presents the first evidence of horses' abilities to spontaneously discriminate between positive (happy) and negative (angry) human facial expressions in photographs. Our results showed that the angry faces induce...

Peganum harmala L. is a plant, which grows in semi-arid rangeland. The plant is used traditionally as an emmenagogue and an abortifacient agent in the Middle East and North Africa. All parts of plant are thought to be toxic and sever intoxication occurs in domestic animals. Digestive and nervous syndromes have been observed in animals that consume sub-lethal amount of the plant. The toxicated a...

The relationship between nasal obstruction and facial growth is controversial. Much of the controversy relates to the lack of sophistication in quantifying nasal versus oral respiration and the lack of longitudinal data. Nevertheless, a number of studies in laboratory animals, nonhuman primates, and humans have shown a relationship between nasal airway obstruction and aberrant facial growth. In...

Interpersonal touch is frequently used for communicating emotions, strengthen social bonds and to give others pleasure. The neuropeptide oxytocin increases social interest, improves recognition of others' emotions, and it is released during touch. Here, we investigated how oxytocin and gentle human touch affect social impressions of others, and vice versa, how others' facial expressions and oxy...

Facial expressions of emotions are important in nonverbal communication. Although numerous neural structures have been identified to be involved in emotional face processing, the amygdala is thought to be a core moderator. While previous studies have relied on facial images of humans, the present study is concerned with the effect of computer-generated (avatar) emotional faces on amygdala activ...
