hello

i just convert the yolo detection using mkl dnn example into c++ using matlab coder witch is only detect an object.

but faceing a lot of problem when i try to integrated with android studio using ndk and android.mk file

any help quick please

android.mk :

LOCAL_PATH := $(call my-dir)
#CLEAR ALL LOCAL VAR EXCIPT LOCAL VAR
include $(CLEAR_VARS)

We don't have link to explain about the workflow. It is more of an offline assmebling which you might have to do. There is no automated way to do that in MATLAB as of today . Please use the below links for android deployment manually.

To build arm compute library for android - Refer to this link

To do the codegen for arm compute use example - link

We are working on bringing the automated android deployment for deep learning networks.

Yes, MATLAB coder is the right toolbox for this work flow.

Thank you,

Praveen.

Thanks a lot One final question does it required ARM processor or it is ok with Intel processor in my laptop ?
