<p dir="auto">I have a caffe model of mtcnn and a caffe model of sphereface. I have built a pipeline that takes an image and produces an embedding of the face. Pipeline is written in c++. On my CPU i5 processor opencv dnn is loading the models and is taking 100 milliseconds for processing. Exactly same code when i deploy on android takes around 20 times more time for execution. I have tried compiling opencv on android using MKL and openblas but i found no different at all in processing speed. Here is my cmake configuration:</p>
<p dir="auto">"-DBUILD_opencv_world=ON -DBUILD_opencv_gapi=OFF -DWITH_NVCUVID=OFF " +<br>

"-DOPENCV_ENABLE_NONFREE=ON -DWITH_NVCUVID=ON -DWITH_MFX=ON"</p>

<h5 dir="auto">Steps to reproduce</h5>
<p dir="auto">Simply take any caffe model and run it on CPU and then use the same code android. Android processing will be a lot slower. I am expecting this to be slow on android but it is absurdly slower in my case. I can expect 4 to 5 times slower performance but 20 times is just not acceptable.</p>

<p dir="auto">I am totally new to OpenCV and I've learnt C++ just to start messing with OpenCV, even though I'm new to the language and the library I've done my reading and think I have a handle on the language, the library however is a different story. Anyways, on trying out the tutorial code from the website I noticed a ton of warnings in visual studio over simple image I/O. I was wondering if this is a normal occurrence and sought an answer on stackoverflow, the general consensus was to raise the issues here.</p>
