Description: 直方图均衡：原始图的直方图变换为均匀分布的形式，这样就增加了象素灰度值的动态范围从而达到增强对比度的效果
中值滤波：中值滤波属于非线性平滑滤波器，它可以消除噪声又能保护图象的细节-histogram equalization : the original plan to transform the histogram in the form of uniform distribution. This will increase the value of the pixel gray areas so as to achieve dynamic contrast enhanced effect of filtering : Median filter is nonlinear smoothing filter, it can eliminate noise while preserving image details Platform: |

Description: 所谓直方图就是在某一灰度级的象素个数占整幅图像的象素比 h=nj/N,其中nj是灰度级在j的象素数，N是总象素数，扫描整幅图像得出的h的离散序列就是图像的直方图，h求和必然＝1，所以直方图可以看成是象素对于灰度的概率分布函数。-Histogram is the so-called gray level in a given number of pixels representing the entire image pixel than h = nj/N, which nj is the gray level of pixels in the j number, N is the total number of pixels, scanning the whole lot images derived from the discrete sequence h is the image histogram, h summation is bound = 1, so the histogram can be viewed as the probability of pixel gray-scale for the distribution function.

Description: 本实验要求编写一个计算图像直方图的程序并要求讨论直方图均衡化技术，最后对图3.8（a）进行均衡化处理。直方图是多种空间域处理技术的基础，直方图操作能有效的用于图像增强。在实验中根据直方图对应的离散函数可以编写出计算一个图像直方图的函数，直方图均衡化则是借助于直方图灰度变换实现灰度映射从而达到图像增强的目的。实验通过得到原始图像的直方图，直方图均衡化变换函数图和增强后的图像增强后图像的直方图这些实验数据来解释图像被增强的原因。-In this study requested to prepare a procedure for calculating the image histogram and asked to discuss histogram equalization technology, the last of Figure 3.8 (a) a balanced treatment. Histogram is a variety of spatial processing technology foundation, histogram operation can be effective for image enhancement. In the experiment under the histogram corresponding discrete function can be calculated to prepare an image histogram function, histogram equalization is a means of gray-scale transformation to achieve gray histogram mapping so as to achieve the purpose of image enhancement. Experiments have been the original image through the histogram, histogram equalization transformation function maps and enhanced image after image enhancement histogram of these experimental data to explain the reasons for the image was enhanced.

Description: 灰度直方图是灰度级的函数，描述的是图像中具有该灰度级的像素的个数。它是多种空间域处理技术的基础。直方图操作能够有效用于图像增强；提供有用的图像统计资料，其在软件中易于计算，适用于商用硬件设备。直方图均衡化是通过对原图像进行某种变换，使原图像的灰度直方图修正为均匀分布的直方图的一种方法。图像灰度 直方图均衡化使得图像的灰度分布趋向均匀，图像所占有的像素灰度间距拉开，加大了图像反差，改善了视觉效果，达到增强目的。MATLAB是数字图像处理的常用工具，应用MATLAB的各种函数能够对数字图像进行各种处理。-Histogram (histogram) is the gray level function, describes the gray level image with the number of pixels, the horizontal axis is the gray-scale, vertical axis is the frequency of the gray scale (pixel)
