Image processing
Image Processing is one of the techniques evolved in the area of imaging that is graphics.
Processing of image, bitmap, video for obtaining useful information. Biometrics is one of the branch of image processing. It involves human or bio pattern detection. It contains lot of algorithms to match the patterns. Normally the pattern was finger print. The finger print is unique one. But there is any injuries and aging problems may happen. So finger print can't be used.
Now instead of finger print, iris(which is a part of a human eye) is used. Iris is captured by camera. Authentication is maintained by pattern matching of existing iris image. This techniques are used in security process of military, government, private premises, police department.
Now lot of research is going on.
