本文给出一个简单的连通域处理函数,当然这个函数是来自OpenCV著名教程Learning OpenCV中,只不过它的接口是基于c版本的OpenCV,而到目前为止,基于C++接口的OpenCV已经是主流,所以我将其接口改成了c++版的,但是其内部一些代码基本没有动它。 开发环境:OpenCV2.4.3+QtCreator2.5.1 实验基础 首先来看这个连通域处理函数的...

1c. It can be seen that the obvious bone outline in the gradient-based sketch map is not clear in this method, and the blood vessel part is clearer than the gradient-based sketch map. We use the OpenCV library for this step. Combine the results of the two processing methods above to ...
OpenCV用数组(通常为vector)来表示轮廓树,其中每个值都代表一条特定轮廓(包含一个四整数组,通常表示为cv::Vec4i)。它们之间的层次关系如下表: 当不存在某种联系时,该联系的值设为-1。 对于cv::findContours()函数,一条“边缘”只是一块非常窄的“白色区域”。对于每一条外部轮廓,总有一条几乎完全相同的孔轮...

For the case of sparse arrays, OpenCV has the alternative data structure, cv::SparseMat. Note If you are familiar with the C interface (pre–version 2.1 implementation) of the OpenCV library, you will remember the data types IplImage and CvMat. You might also recall CvArr. In the C++ ...
