一篇关于灰度转换的论文：该文介绍了用直方图均衡化对灰度图像进行灰度映射，从而达到使图像增强的目的。利用VC++6.0执行效率

高，可继承、封装、移植等成熟的软件技术，对直方图均衡化算法进行实现。实验表明，该程序可以快速、准确地对灰度图

像进行灰度变换，达到了使图像对比度增强，改善图像质量的预期目的。-On a gray-scale conversion of paper: This paper introduces the use of gray-scale histogram equalization for gray-scale image mapping, so as to achieve the purpose of image enhancement. VC++6.0 to implement the use of high efficiency, inheritable, packaging, transplantation, etc. software technologies mature, the histogram equalization algorithm to achieve. The experiments show that the program can quickly and accurately carried out on the gray image gray-scale transformation to make the image contrast enhancement to improve the image quality of the desired purpose.
