Description: 图像预处理中，通常采用直方图均衡化[1]和直
方图规定化、线性和非线性灰度变换法[2]提高图像
的对比度，但效果均不理想。故提出一种对比度增
强算法。该算法首先对直方图进行平滑处理以消除
直方图中因噪声而引入的随机干扰点，然后进行直
方图均衡化，增大图像的对比度，接着在整个显示
范围内对图像灰度级进行等间距排列，使输出图像
的灰度动态范围达到最大灰度变化范围，最后对整
幅图像中值滤波，滤除图像中被增强的噪声。-Image preprocessing, the commonly used histogram equalization [1] and histogram specification, linear and nonlinear gray level transformation method [2] to improve the image contrast, but the results are not satisfactory. It presents a contrast enhancement algorithm. In this algorithm the histogram is smoothed to eliminate the histogram due to the introduction of random noise and interference points, followed by histogram equalization, increases the contrast of the image, then in the context of the show were equally spaced gray level image arrangement, the output gray level dynamic range for maximum gray level range, and finally to the whole image median filter, filter out the noise image is enhanced.

Description: 这是个图像处理的源代码，是本人自己编写的，实现的功能如下：
锐化、边沿检测：套用模版。另外还有一个自定义模版，供用户自行设计模版运行，从而实现其他功能，如线检测。
浮雕：本像素减相邻像素，再加一个常数得到的。
直方图均衡化则套用步骤，根据课本步骤来编写。
提取轮廓：若该点为黑点，八邻域也为黑点，则就把该点变白。
阈值分割分为固定阈值分割（即二值化）和动态阈值分割（切割若干子图，求均值，该均值即子图的阈值）。
区域生长：把种子和4邻域的点分别比较，两者之差小于阈值，且该4邻域点第一次出现，就把该点入队列。比较完毕后从队列提取像素点，继续进行上面操作，直到队列为空。
图像投影：先二值化，统计每一行（或每一列）黑点数目，向左（或向下）显示黑点
图像旋转：套公式，目标点跟源图像的点有对应的转换公式，可以实现任意角度旋转。
-This is a image processing source code is written in my own, to achieve the following functions:
Sharpening, edge detection: Apply template. There is also a custom template for users to run their own design template in order to achieve other functions, such as line detection.
Relief: the adjacent pixels by the pixels, plus a constant to get.
Histogram equalization is applied step, according to the steps to write textbooks.
Extracted contour: If the point of black spots, eight neighborhood for the black point, then put the white point.
Thresholding segmentation into a fixed threshold (ie, binary) and dynamic threshold segmentation (cutting a number of sub-graph, find the mean, mean that the sub-graph of the threshold value).
Regional growth: the seeds and 4 points respectively neighborhood comparison between the difference is less than the threshold, and the four neighboring points the first time, put the points into the queue. After comparing pixels extracted from the queue Platform: |

Description: 如果一副图像的像素占有很多的灰度级而且分布均匀，那么这样的图像往往有高对比度和多变的灰度色调。直方图均衡化就是一种能仅靠输入图像直方图信息自动达到这种效果的变换函数。它的基本思想是对图像中像素个数多的灰度级进行展宽，而对图像中像素个数少的灰度进行压缩，从而扩展像原取值的动态范围，提高了对比度和灰度色调的变化，使图像更加清晰。-If an image pixel occupies a lot of gray level and evenly distributed, so such images tend to have high contrast and varying shades of gray. Histogram equalization is a kind of input image histogram information alone can automatically achieve this effect transformation function. Its basic idea is the number of pixels in an image more gray-level broadening, while the number of pixels in the image of a small gray compress like to extend the dynamic range of the original value, improved contrast and gray tones changes to make the image clearer.
