A RMB optical character recognition system using FPGA

Optical Character Recognition (OCR) is an important area of pattern recognition. Automatic OCR system is one kind of intelligent system which is very important to the current automation systems such as ATMs. In this paper, a RMB OCR (ROCR) system is implemented using FPGA, which consists of Character Segmentation (CS) module and OCR module. The CME M7 was used for the implementation. 83.30% Logic Elements (LEs) of a M7 FPGA was used for the system implementation. The whole system runs with a maximum frequency of 100MHz and is capable of processing one image per 6ms with the successful recognition rate at 98.45%.
