摘 要

   本文主要涉及到数字图像处理中最常用的直方图处理。从应用角度上来说，直方图是多种空间域处理技术的基础，直方图操作能有效地用于图像增强，除了提供有用的图像统计资料，在其他图像处理应用中也是非常有用的，如图像压缩与分割，直方图在软件中易于计算，也使用于商用硬件设备，因此，他们成为实时图像处理的一个流行工具。本文主要介绍直方图处理的常用方法。主要内容有：对直方图进行介绍，了解直方图的基本概念。对图像进行直方图均衡化，实现图像增强，并针对均衡化的不足之处，对直方图进行规定化处理，最后实现过程在VC++环境下进行调试。实验结果表明，该方法是一种既简单又实用的图像处理方法。

Abstract

 This article relates to digital image processing most commonly which used in the histogram processing. From the application point of view, the histogram is a variety of space domain processing technology foundation, histogram operation can be used effectively to enhance the image, in addition to providing useful image statistics, in other image processing applications are also very useful, such as Image compression and segmentation, in the histogram in the software easy to calculate, but also for use in commercial hardware devices, so they become a real-time image processing of a popular tool. This paper describes the common methods of dealing with histogram. Elements include: a presentation on the histogram, histogram understand the basic concepts. The image histogram equalization, and image enhancement and balanced view of the inadequacy of the provisions of the histogram to deal with, the final realization of the VC + + debugging environment. Experimental results show that the method is a simple and practical method of image processing.

Key words:Histogram, histogram equalization, the provisions of the histogram
