Abstract
A new hardware implementation of histogram equalization by means of Field Programmable Gate Array (FPGA) is presented. Histogram equalization is an effective means of image enhancement. Its real-time processing requires a great deal of memory and very high processing speed. The logic cell nature of XC4000 family's FPGA is most suitable for performing real-time pixel-level image processing operations such as histogram equalization. A core is constructed to complete this histogram statistics and histogram equalization. As a result, the chip makes circuits and system more effective than ever, and it takes very short time to complete the calculation and generate the look-up table. The equalizing technique is described and implementation results using a Xilinx XC4010 FPGA are presented.
