use module form opencv contrib in c++

opencv-contrib

asked 2020-03-23 23:33:51 -0600

I'm trying to use the anisotropicDiffusion() function from the ximgproc module in opencv contrib but I am having problems loading it into my editor codeblocks or G++ on Ubuntu 18.04. In general, how do I install a module from opencv contrib to be able to use it?

Also, opencv seems to reference from the following location /usr/include/opencv2/. When I did my original make install it built most of my hpp files under /usr/local/include/opencv4/opencv2/. How do I have my machine look for the hpp files under /usr/local/include/opencv4/opencv2/?

can't help wirh any IDE, but for opencv4, your include path should be

/usr/local/include/opencv4/

then use headers like

#include "opencv2/core.hpp"
#include "opencv2/ximgproc.hpp"

Anyone know how to modify the path in Ubuntu to use the above path instead?

it is your "include path", used with g++ cmdline like:

g++ -I/usr/local/include/opencv4/ .......
