i’l learning opencv with c++ and so i’m trying to use new c++ interface. but a lot of code i found on internet is based on old c interface.

for example i fond a lot of algorithm based on

IplImage, cvCvtPixToPlane, cvThreshold

and i have to translate them in

cv::Mat, cv::threshold, ..

in here (i think the official manual) i haven’t find anything of really complete.

and each time i have to google for get the right conversion in the new c++ interface.
where can i find a conversion table?

Try OpenCV manuals, It seems they are the best way to find equivalent functions.

All C,C++ and python API is available as single pdf, so you can just search for function names to find equivalent in C or C++
