FPGA Implementation of real-time adaptive bidirectional equalization for histogram
According to the characteristics of infrared images,a contrast enhancement algorithm was presented.The principium of FPGA-based adaptive bidirectional plateau histogram equalization was given in this paper.The plateau value was obtained by finding local maximum and whole maximum in statistical histogram based on dimensional histogram statistic.Statistical histogram was modified by the plateau value and balanced in gray scale and gray spacing.Test data generated by single frame image,which was simulated by FPGA-based real-time adaptive bidirectional plateau histogram equalization.The simulation results indicates that the precept meet the requests well in both the image processing effects and processing speed.
