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
