摘要： 图像分割属于当今社会多种多样的图像处理方法的基础部分，对图像分割的研究也已经持续了相当长的时间，也一直是相关领域的重点。因此图像分割的方法也多种多样，主要有基于边缘的图像分割，基于区域的图像分割等基于不同的算法的图像分割形式。本文中将会介绍一种基于直方图的图像分割系统，对这种单一的图像分割方法进行较为全面精细的阐述跟实践。即通过对直方图中像素的灰度值分布在直方图中找到两个峰，使用双峰法来实现对图像的分割。本次设计中选择使用MATLAB来完成仿真和分析。33070

在研究本次的系统中我发现任何一中单独的图像分割方法都不可能普遍的适应各种各样的图像分割环境的需要，而单一一种的图像分割方法也往往不能达到预期的图像分割算法。所以之后将多重的图像分割算法进行同时使用，才可以打到较好的图像分割的效果，然而这远远不够，还是不断的有人提出新的图像分割的算法。这说明了图像分割在优化跟适用性上任然有很长的一段路要走，依然有大量的学者认为现行的图像分割算法并不成熟，在新出现的图像分割算法中，有很多为了适应在医学中广泛运用的图像分割，使用了基于小波变换的图像分割。在医学方面图像分割的地位几乎可以说是不可动摇，不管是CT还是核磁共振以及医学研究所用的显微图像的处理，都离不开图像分割，所以图像分割的前景值得我们所有人共同努力。

Design and implementation of the system of image segmentation based on histogram
Abstract: Image segmentation is nowadays one of the variety of image processing method, the study of image segmentation has been going on for quite a long time, however has been the focus of related fields. As we all know image segmentation methods are varied, and there are some most wild used method based on edge,field and other different type of image segementation. This dissertation will introduce a image segmentation system based on histogram, in this dissertaion ,i will show you a comprehensive illustration . Through the histogram of pixel gray value distribution find two peaks in the histogram with a bimodal method to complete the image segmentation. i choice to use MATLAB to complete the simulation and analysis.
In the study of the system I found in any single image segmentation method can not be generally adapted for a variety of image segmentation, and a single image segmentation method also often fail to achieve the desired image segmentation algorithm. So after the multiple image segmentation algorithm was also used to hit better image segmentation effect, yet it's far from enough or continue to have proposed a new image segmentation algorithm. This shows that the image segmentation in the optimization and application of office though there is a long way to go, there are still a large number of scholars think the current image segmentation algorithm is not mature, the new image segmentation algorithm, there are a lot in order to adapt to the widely used in medical image segmentation, the use of the wavelet transform of image segmentation based on. In the status of medical image segmentation can almost be said is unshakable, whether CT or MRI and medical research of microscopic image processing, are inseparable from the image segmentation, so image segmentation of foreground is worth all of us to work together.
