Became a computer to recognize 21 different facial expression

U.S. researchers found a way to determine the definition of the computers on the 21 expression of the human face , some of them complex , the discovery hailed by many as a major advance in the field of cognitive analysis .And prepared this team of researchers at Ohio State University in the northern United States , a way to allow computers to reveal the number of facial expressions equivalent to three times the current number .From 6 to 21 different expression
The Alex Martinez , a researcher in cognitive science : We went beyond the facial expressions used to express their feelings just as simple as joy or sadness .We found a large homogeneous in a way that moves the muscles of people and faces to express 21 different categories of emotions .He pointed out that this is simply stunning .This means that these feelings of the 21 are expressed in the same way from almost everyone , at least in our culture .This may allow the study, published in the reports of the National Academy of Sciences, to help diagnosis and treatment of mental disorders such as autism or anxiety syndrome, post-traumatic stress .Even today , the researchers reckon their studies on the 6 basic feelings of joy , sadness , fear , anger , and shit .And enables researchers from Ohio State University to expand this set of emotions that are identified after it photographed facial expressions 230 volunteers after receiving indications Sounds like I have received the good news just unexpected or Chmon very smelly .Track the movement of the eyes and mouth
And allowed a careful analysis of the 5 thousand files in this test to reveal alterations in the main movements known to the facial muscles , including those issued at the corner of the lips or in the upper part of the eyebrow .And mayors of scientists to analyze the data the aid of device called Veichl Action Coding System or facial movement coding system used in the analysis of body language , so as to survey the similarities and differences in expressions .Thus, they were able to identify 21 categories of emotions consisting of 6 major feelings in addition to the feelings of different combinations .For example, the response was one of them when you received good news is expected to show the feelings of pleasant surprise .In these cases , the researchers identified expressions of joy for the movement of the cheeks and smile broadly eye iris and open mouth .In 93 % of cases , participants showed feelings of pleasant surprise through a combination of reactions .
