Information analysis and processing are an important part in information optics. It is becoming an urgent challenge to rapidly search and analyze desired information from mass information. Joint Fourier transform is an image recognition technique with high information throughput, fast processing speed, and accurate recognition capability. It has been successfully applied to many fields. Through this system, users can understand the basic principle of Fourier image recognition, familiarize with the construction of a Fourier image recognizing system, and expand the system for more advanced research applications.
