求图像的二值化最佳阈值
- 求图像的二值化最佳阈值 利用opencv 实现图像的膨胀,腐蚀,开运算,闭运算,求轮廓操作,并可以从外部文件导入结构算子-Find the best binary image threshold image using opencv achieve dilation, erosion, opening operation and closing operation, find the outline of operation, and can be imported from an extern
基于opencv2.2的大津法分割
- 基于opencv2.2的大津法分割,大津法是一种自适应的阈值分割方法,应用较广,按灰度特性,将图像分为背景和目标两部分,是二值化的图像。本代码需要先行安装opencv2.2-The Otsu method based opencv2.2 split, Otsu method is an adaptive thresholding method, used widely, according to the gray-scale features, the image is divided into
SubImage IplImage对象或者BYTE型数组中取出一幅图像的子图像
- 用于从一个IplImage对象或者BYTE型数组中取出一幅图像的子图像,类似于OpenCV中的SetImageROI,但是该函数提供的功能是原图像子图像的一个拷贝,而非在原图像中设置ROI。-For the IplImage from a BYTE array object or remove an image of the sub-image, similar to OpenCV' s SetImageROI, but the function is the function of the o

SnakeProfile
- opencv例子里没有提供cvsnakeimage的使用方法,在此整理一个例子,可以形象的看看snake算法的结果,大致做法是: 首先设定域值分割,把基本的轮廓找出来,见图中蓝色轮廓线,再将轮廓点传入cvSnakeImage函数,计算出绿色的snake轮廓线。 其中参数alpha代表点相互靠拢的权值(0-1.0),beta表示弯曲能量(越小越容易弯曲)(0-1.0),gamma表示整体能量(0-1.0)。其中参数我自己也不确定具体的范围,最好自己更改不同的范围试试. -o

- 直方圖等化(Histogram Equalization)為一種使用統計方法的影像處理程式設計,它的功能為將統計直方圖的色彩分布平均的打散在直方圖裡,也就是說,讓一張圖的直方圖分布均勻化,同樣的也是使用到LUT(Look-up Table)的方法 而在設計直方圖等化不可或缺的就是需要先知道統計學的機率密度函數(Probability Density Function,PDF)以及累積分配函數(Cumlative Distribution Function,CDF)相關的基本概念,在這邊
