Patern recognition in embedded systems

摘要

The article describes the principle and design of a standalone, mobile processing system which performs optical character recognition (OCR) in images acquired from a video camera. The system includes a powerful digital signal processor and implements image enhancements and pattern recognition algorithms. The device has IP Ethernet interface and is suited for remote applications, with low power requirements, high performance and low cost. Applications such as Automatic License Plate Number Recognition (ANPR), Automatic document electronic transcoding, and others can be accomplished using this system.
