Algorithm research of infrared target recognition

Target recognition is an important content of computer intelligent vision surveillance system. A method of joint transform recognition is proposed for identifying and tracking the target from the infrared thermal image, which based on wavelet packet, Laplace operator and Fourier transform. The experimental result shows that the algorithm has a good performance in real-time, moreover, it can recognize the target accurately neither variety sizes nor cluttered backgrounds. And the algorithm can also solve the problem of slow speed and false recognition in infrared target detection effectively.
