摘　　要：文中基于图像增强方法及其实现进行了研究。首先阐述了传统的直方图均衡化方法存在的问题,进而提出了改进的自适应直方图均衡化图像增强算法。采用空闲灰度级动态分配的自适应直方图均衡化增强算法,并将该算法移植到本文搭建的DSP硬件实验平台上进行验证,实验表明,该算法显著的改善了图像的视觉效果,使图像更清晰,且算法计算简单,硬件实现容易,在图像处理应用中十分可行有效。This paperstudy the image enhancement method and its realization. Firstly, it describes the present problems of traditionalhistogram equalization method, then proposed the image enhancement algorithm of improved adaptive histogram equalization. Useing free grayseale dynamically allocated of the image enhancement algorithm, and the algorithm was transplanted into the DSP hardware platform for verification, experiments show that, this algorithm improves the visual effects of the image, the image is more clear, and the algorithm is simple, easy for hardware implementation, in image processing applications very effective.
