New image processing system detects and classifies human facial expressions
Diabetes and high levels of blood sugar may be linked to abnormalities in a person’s body clock and sleep patterns, according to a genome-wide association study published today in the journal Nature Genetics. The research suggests that diabetes and higher than normal blood sugar levels could partly be tackled by treating sleep problems, say

Who knows what evil lurks in the hearts of men? Dr. Prabir Bhattacharya and his computers might. He and Concordia graduate student Abu Sayeed Sohail are developing a computer image processing system that detects and classifies human facial expressions.
The aim of this system is to take and analyze photos of individuals, potentially in areas of high traffic where security is a primary concern, such as an airport. If one could take random photos of the crowd and process them fast enough, there is the potential to identify those individuals who might be problematic.
Facial expressions do not actually involve the entire face, but rather specific sets of muscles under the face near the eyes, nose and mouth. Bhattacharya and Sohail’s system measures 15 key points on the face and then compares these measures against images of identifiable facial expressions. Although there is great variety in expression across both individuals and cultures, the pair has identified seven basic expressions that seem to be relatively universal.
Joyful or sad smiles expressed after a competition are the same for blind and sighted athletes, says a new study, showing that certain facial expressions are innate and managed differently depending on the social situation. “Spontaneously produced facial expressions of emotion of both congenitally and non-congenitally blind individuals are the same as for sighted individuals

Surgeons in the United States have carried out America’s first face transplant at a clinic in Cleveland, Ohio where a woman has had 80% of her face replaced with that of a deceased female donor. The operation which was conducted by reconstructive surgeon Dr. Maria Siemionow along with a team of seven other doctors, is

Michael J. Tarr, a Brown University scientist, and graduate student Adrian Nestor have discovered this color difference in an analysis of dozens of faces. They determined that men tend to have more reddish skin and greenish skin is more common for women. The finding has important implications in cognitive science research, such as the study
