C++ 用opencv生长的种子区
我需要选择一个像素值,并根据种子像素应用区域增长。在尝试编写代码之后,结果总是一个黑色图像 不管我用什么种子点。整个问题涉及C++ 用opencv生长的种子区,c++,image-processing,opencv,C++,Image Processing,Opencv,我需要选择一个像素值,并根据种子像素应用区域增长。在尝试编写代码之后,结果总是一个黑色图像 不管我用什么种子点。整个问题涉及GrowColor函数。我的猜测是ifs的逻辑错误 #include <cv.h> #include <highgui.h> using namespace std; int xDim, yDim, zDim; float ThreshHold = 45.0; unsigned long total[3]; int coont, tt; IplI

递归函数可能会导致无限循环。检查该函数中的代码一次。很好。插入几个断点来查看代码的进度可能是值得的。
