Age Telling Software

New software has been developed designed to tell an age of a person by just taking picture of him. The assessment of an age would be made through an appearance of that person. However precision is not guaranteed.
This software is developed in University of Illinois, Urbana-Champaign. The developers of this software trained it through feeding pictures of 1,600 people. They gave five pictures for each person to the system; it means that record of 8000 pictures is given to the software. Age range of these persons is from 1 to 93 years. You can assess better that this software is able to tell any age.
The software functions with computer; after taking picture of a person it matches it with it a record given to it and this enables it to tell about its assessment. Gray scale plays a major role in the assessment process. For example, if an image is having dimension of 100 X 100 pixels, it means that there are total 10000 numbers of pixels in a picture. Each of the pixels is having its separate level. Each level depends on darkness and lightness of its gray scale. The software works on each pixel and collectively gives its result.
This software also determines shape of face of a person. It recognizes eyes, nose, ears, and shape of mouth also. This additional information is also very helpful in telling an age. It is told that it also assesses gender of a person and determines his emotional expressions also (like smile, surprise or negative emotions). Almost 90 percent of its results are seen to be accurate.
Many large companies are approaching Huang to get this software. Huang says that this software will be very useful in future for security companies. It will replace present technologies of fingerprints and palm vein scans. It could be used at ATMs and at entrances of buildings with other technologies to better safeguard the security.
Huang and Philips are doing some additional research to avoid requirement of any extra hardware like camera or special lighting. One problem which is being tried to solve is that it only works if the face picture is captured from straight direction. The researchers are trying to refine this software more, that it could be able to read face from any direction. It is hopefully said that in near future it will be ready for commercial use.
