SCIENTISTS AT the Centre for Development of Advanced Computers (CDAC), Kolkata, are working on an innovative idea in biometric identification systems. Till now, the chief objective of biometric studies has been voice, iris, speech and fingerprinting identification.
Senior CDAC scientist Dr Debashish Mazumdar said a group of scientists were developing a biometric technology system that would focus on emotional expressions exhibited by a person. Psychologists have already proved that there was a close co-relation between emotional expressions and the personality of a person.
For example, Dr Mazumdar said when a person laughs, the corners of the lips tighten, the eyes look different and the cheeks change colour. Similarly, in other emotional stages, several prominent changes are witnessed on the face of the individual. He said research on application of emotional expressions in biometric identification processes has attracted global attention and a few countries have expressed desire to collaborate in research project. Meanwhile, he added, the CDAC was developing software which could identify frontal images for identification purposes. The software was in the trial process.
Another CDAC scientist, Dr Soma Mitra said a team of scientists was developing a system for taking images of the face from different directions. At present, images are only frontal from an angle of 90 degrees. Dr Mitra said it would take a long time to develop biometric recognition systems for taking photographs of the face from different angles. In the first phase, the frontal image recognition system, has been developed and efforts were on to develop a comprehensive software to carry more than 40,000 images. Later, Dr Mitra presented her research paper on ‘Computing asymmetry biometric of frontal human face image using phase congruency fourier series’ at the Biometrics Workshop at IIT-K here today .
