using dlib in FPC/Lazarus for face recognition?
«

Hi,
i'm very impressed from the facial recognition library in python. It seems that the python facial recognition library is based on
dlib.net
library. Does someone know how to use the dlib library in Lazarus?

If you could provide a sample of some feature utilized from that LIB in other languages I am sure it could be duplicated.

facial recognition library
:
Code: Python
[Select]

[-]
import
face_recognition
face_recognition.
face_encodings
face_recognition.
compare_faces
face_recognition.
faces_distance

Usually if the library has a C interface, just port the interface and you're done. But, dlib isn't one of them. It has either C++ or Python only, no flat C interface available.
I think you better off with TensorFlow as it has various Pascal/Delphi wrappers already, but choosing which one is an adventure itself

AFAIK, the Python example imports a part of the library written in C\C++ and named "Dlib" (
dlib.net
: C++ toolkit for machine learning algorithms
), part concerning the "face detection" problem: Cf.
http://dlib.net/face_detection_ex.cpp.html
.
It should be possible to do the import in Object Pascal of the C header files (Object Pascal can do that) as dlib/image_processing/frontal_face_detector.h, in order to use this library in Lazarus.

use: Linux 64 bits (Ubuntu 20.04 LTS).
Lazarus version: 2.0.4 (svn revision: 62502M) compiled with fpc 3.0.4 - fpDebug \ Dwarf3.

First of all thanx for your answers. Because the dlib.net library is written in C I downloaded the Visual Studio Community 2019 and made a DLL, which exports the function as a flat function.
I have attached a sample project with 2 DLLs( for 32bit and 64bit). Furthermore you need to download and decompress the following files in the same directory as the project1.exe:
dlib_face_recognition_resnet_model_v1.dat ...
http://dlib.net/files/dlib_face_recognition_resnet_model_v1.dat.bz2
shape_predictor_5_face_landmarks.dat ...

I have posted a Delphi version in the german
Delphipraxis.net
forum too.
