Digital Image Processing and Biometrics Based Human Identification Systems

The process of receiving and analyzing visual information by digital computer is called Digital Image Processing and Scene Analysis. Digital Image Processing is a prevalently evolving field with growing applications in Science and Engineering. Image Processing holds the possibility of developing the ultimate machine that could perform the visual functions of all living beings. Many theoretical and technological breakthroughs are required before building such a machine i.e., there is an abundance of Image Processing applications that can serve mankind with the available and anticipated technology in the near future. Imaging began in the 19 century with photography and continued with X-rays, television and electronic scanning in the 20th century. Image Processing as a field of study began in 1950s with pictures of the earth from high-flying spy airplanes and then with pictures of the earth’s surface taken from orbiting satellites.
