can you tell me how you optimized the dlib ?

Hi, here are the concept applied in this project 1. multi-threaded dlib 2. lower number of pyramidal layer I will send you a source code asap :) 2017. 5. 25. 오후 12:21에 "周华" <[email protected]>님이 작성:

can you tell me how you optimized the dlib ? will you provide the source code? — You are receiving this because you are subscribed to this thread.

lower number of pyramidal layer

does that means doing face detection?

now my porblem is mainly on landmark predictor part.it's quiet slow.about 150-200ms.

I don't know why..

davisking/dlib#604
this is the process I did.
I use the code of dlib version 19.1 because I cant get through the version 19.4 on simd part's compile.

I found the solution,...I should build the project in release mode..

Good work ! Actually, predicting landmark points is not a time-consuming work because dlib supports it. If you want to make a fast face predictor, you have to reduce the time cost of detecting faces. That’s a critical part :) There are many ways to optimize the application, such as resizing the image, making a grayscale image, using a NEON architecture, Compiling release mode ... You did it on Android platform ?

yes,on Android device.
did you integrated the NEON support ?
I use the 19.1 source code of dlib, because I cant compile the 19.4 through.the simd fils always get errors.

I use the opencv to do face detection, I can optimize it to under 10ms and still usable.

did you eat 粽子 these days btw? :-)

Hi, 周华 I’m looking for the ways to port android-version(NEON support) @fastfastball said that he did it ! Here is the repo https://github.com/fastfastball/dlib_for_arm <https://github.com/fastfastball/dlib_for_arm> But, when I replace original one(19.1) with new one(19.4, simd). Error occurs. Maybe it needs to be setting the Android.mk, Application.mk file Test it ! If you successfully compiled, please let me know asap :) Thank you.
