Advanced high speed optical pattern recognition for sur-veillance systems

Abstract

Today security is the prime factor needed in all civic places such as Airport, Railway station and Bus stations. Due to absence of extremely fast security systems, lots of damage to human life and public properties were seen in last decade. The proposed design able to capture, recognize and detect the unauthorized person at high speed. The aim of this research work is to design a system that recognizes the pattern at high speed. The 4f system is an image focusing system with intensification factor of unity which can be demonstrated using ray tracing. The 4f system is simulated in MATLAB. Further it can be extended to advanced extremely fast pattern recognition surveillance systems. The optical Fourier transform is performed between the cameras captured image and the conjugate of the database image which is multiplied and projected on the Fourier plane. This provides a pattern recognized image at the output plane at extremely fast rate.
