A new system for image signal processing and pattern recognition is presented in this paper. It was implemented in Windows 98 platform with a CMOS image sensor of USB interface. In the integrative signal processing system, visual pattern is firstly captured as digital image signal by CMOS image sensor, and then packaged into frame signals for transferred to VFW (Video for Windows) application through USB interface. At last, it is processed in VFW application for recognition by using the method of moment invariant extraction. The whole system architecture and its signal processing mechanism will be described in detail in this paper.
