XILINX BASED HARDWARE FOR PICTURE PROCESSING AND CHARACTER RECOGNITION PURPOSES

Abstract

The paper deals with the development of hardware that is capable realising picture pro- cessing and character recognition algorithms. The hardware was implemented as an IBM PC peripheral card and contains up to five XILINX XC 3090 FPGA devices. Because of the on board reconfigurability of the XILINX devices the hardware allows to imple- ment several separate algorithms at different times. For evaluation the performance of the hardware the Dineen and the linger image smoothing techniques were chosen. The image smoothing techniques can be used at the pre-processing stage of the character recognition process.
