I am a new OpenCV user. My project would be to detect and extract text from a video. Is there such module allowing this ?

As long as you build OpenCV from source code and you enable the contrib repository, then yes, there is an OCR module available.

But if you are new to OpenCV, good luck with getting it all to work, even experienced users find contrib modules challenging ...

Thanks! And about how much time does it take to recognize a ten-letter long sentence on a quite performant laptop?
