Hi, I'm testing your code in android platform.
I heard that you tested dlib with dlib-android
How did build it with NEON support?

I need to know the details about - Application.mk, Android.mk file
I tested, but I can't build because simd file is added.
Thank you for your contribution :)

When I run the program, I encountered the error of "bus error ". Do you have any suggestions ?

object_detector.h line 445

Minor nit, you've included the python-examples but didn't include the .cpp examples directory. Any particular reason? It would seem that from a software maintenance standpoint, it's easier to preserve as much of the upstream code as possible so changes are easier to ingest.

Is mmod_loss supported/going to be supported in this library?

Also, can the NEON instructions speed up detection on deep neural networks in dlib?

Hi, I'm making a app which detects faca landmark.
I' heard you contributed the performance of dlib.
I want to use your code, but I fail to build it.

1. clone https://github.com/tzutalin/dlib-android
2. replace dlib repo with your dlib_for_arm (rename with dlib)
3. build with android version as described in https://github.com/tzutalin/dlib-android

But, It doesn't compile with
error: ./obj/local/armeabi-v7a/objs/android_dlib/jni_face_det.o: multiple definition of 'dlib::currentTimeInMilliseconds()'

can you give some advice?
I wanna upgrade my app. Thank you for your contribution

Hello,

I have built all the dependencies, so do you know why this problem occurs?
Thanks

I'm trying to incease the fps of the output videos from dlib and decrease the detection time. I had been looking it for hours now and then stumbled upon this. I'd love to talk and know more about it. Any way to contact?

It's said the newest dlib version also supports neon. so what is the difference with yours. which files do you modify.
readme file said :reduce work load : only use 1 filter(front looking) instead of 5 filters in frontal_face_detector.h （so，witch file is modifyed,? there is no difference between your frontal_face_detector and dlib-19.4 frontal_face_detector ）
thread level parallelism : use 3 threads to do face detection ( is any example?)
SIMD : use arm neon to implement dlib/simd/( merge with the newest dlib version ?)

hi -- experimenting with this now (trying a variety of fixes for dlib / android / speed)

I am trying to locate this:

reduce work load : only use 1 filter(front looking) instead of 5 filters in frontal_face_detector.h

in the code but I can't find this modification. The modifications for thread are easy to spot.

can you let me know where to look? thanks much!

thanks for your great work, and how to compile with __ARM_NEON parameter with cmake?

Hi,

What is the status of this project?
