Hi forum,

I am unable to use the warpPerspective function due to this error #include "opencv2/nonfree/nonfree.hpp": No such file or directory.

Can someone tell me the easiest idiotproof way to get it to work without using cmake ? I have no idea what cmake is and how to use cmake. My visual studio got ruined the last time I tried to use cmake without a proper tutorial. I have 0.000% understanding of cmake and I do not want to ruin my visual studio again as I had so much problems setting it up.

I guess in the worst case scenario I will just code out the transformation myself but I thought I should just ask here first.

Thanks

wrapPerspective is included in imgproc not in nonfree module. How have you ruined your visual sudio with cmake?

You are right. You just saved my life. I thought it was under the nonfree module when I followed a certain tutorial online.

The tutorial used SIFT, which i guess is under the nonfree module. I am not using SIFT though.

I think you are not using opencv 3.0. If you're interested with nonfree module you can have a look here or here
