摘　　要： 为了解决图像对比度低和传统的直方图均衡化算法处理速度慢的问题,提出了一种改进直方图均衡化算法及FPGA系统。该系统首先在算法进行改进,达到提高了图像增强的目的,其次系统算法应用FPGA视频处理平台上进行硬件实现,实验结果表明:改进算法能产生比较清晰的图像,图像细节保留较好,达到了图像增强的目的同时简化了系统的结构和设计复杂度,节约了35%的硬件成本,可以满足图像处理的实时性要求。 To solve the low image contrast and traditional histogram equalization algorithm for the problem of slow processing speed, an improved histogram equalization algorithm and FPGA implementation system is designed. The image enhancement is improved based on the algorithm, and the improved algorithm implements FPGA video processing platform realization hardware, experimental results show that this improved algorithm can produce clearer images, and image details of the processed image are well preserved, reach the purpose of image enhancement while simplifying the structure and design complexity of the system, save 35% of hardware costs and meet currently standard image for the real-time requirement and high lighted. The algorithm meets the real-time image processing requirements.
