yeah i guess. So i have to include caffe library and code from there with opencv right?

If that's what you are comfortable with, yes. According to their documentation, you could load Tensorflow, Caffe, Darknet and Torch models

yeah but thats on cpu. which takes alot of time. I have done it. And single image takes about 150ms

Well, you can use either of the other machine learning libraries with GPU for the machine learning portions then OpenCV for the image processing

yeah true. But I want to use Dnn to extract the features. Well thanks anyway.

No in OpenCV 3.3.

I don't think cuDNN will be integrated into OpenCV as it targets only Nvidia GPU. The trend should be to use instead:

This seems to be still in early stages, don't expect to get the same speed than cuDNN in OpenCV 3.3.

Disclaimer: I am not at all related to the development work, this is just my own perception of the project.

my 1st answer was NO, too, but there is this mysterious comment here...

So what does it mean?

@NoobProgrammer refer to the above comment. Test it out and let me know if it works so I can update my answer

ok ill do it later

NoobProgrammer gravatar imageNoobProgrammer ( 2017-10-19 08:37:58 -0500 )edit

So how will i do it? :P as my name suggests i am noob :p

NoobProgrammer gravatar imageNoobProgrammer ( 2017-10-19 08:39:53 -0500 )edit

apologies for (only) adding to the confusion ...

i don't know either. take it more as a hint, that devs there are considering this, and that it's WIP.

answer for now is still: NO.

No worries bro. Thanks again
