Java Kazemi Landmarks
I'm trying to make an application with opencv that is able to recognize a person's face in an image, so I'm trying to use the FacemarkKazemi function of opencv. My problem is that as soon as I switch to class initialization, my application crashes instantly.
You can find the code I'm trying to run here :
https://github.com/opencv/opencv_cont...
The application crashes at line 29 here :
Facemark fm = Face.createFacemarkKazemi();
And i have this error :
java.lang.UnsatisfiedLinkError: No implementation found for long org.opencv.face.Face.createFacemarkKazemi_0() (tried Java_org_opencv_face_Face_createFacemarkKazemi_10 and Java_org_opencv_face_Face_createFacemarkKazemi_10__)

Also, if you know a better way to make FacialMarks, I would be happy to know it.
I added this line to my gradle to import opencv contrib, do you think the error could be due to this?
implementation 'com.quickbirdstudios:opencv:3.4.4-contrib'
Im sorry but I don't think it's a problem with my IDE, the error is when calling the function at runtime on my application. I think the problem is that he can't make the link between java and c++ functions. Can you tell me how you imported the repo from opencv-contrib into your project? I think my concern should come from my import of the gradle.
yea, sorry, replace "IDE" with "toolchain".
i think so, too. unfortunately not using gradle at all, so i don't know.
I'm going to ask another question here to avoid opening another topic, but so I try to compile Opencv with contribution thanks to MinGW by following the following tutorial:
https://zami0xzami.wordpress.com/2016...
But it happens that after the execution of the build I can't execute the mingw32-make command I have the following error:
mingw32-make: * No targets specified and no makefile found. Stop.
I specify that when I put the option CMAKE_TOOLCHAIN_FILE my compilation does not work.
oh, you never mentioned android explicitly before ;(
Ow sorry, I thought I said it. :(
well, anyway, the error says, that the java part has something about kazemi, but the c++ so's have no match for it. can you check your build / install pipeline again ?
I have tested with other functions and it has not only to do with Kazemi, it happens that when I try other functions like LBF there is the same kind of crash / errors. When I go back to where the error goes, in the code there are lines of code without implementation like the following:
During the installation on my android I have absolutely no errors and during the build of the gradle I have no errors either a priori. That's why I question the functionality of the gradle link and try to build opencv myself.
After compiling opencv myself I find myself with the same error. I'm a little desperate.

-- seriously ? no wonder you are in trouble with native libs. (i think, what you're trying is too complicated)Yes I know, but for the moment I really don't have a choice. I have to use native react but I need some features that I have to do natively (like facial landmarks for example). A priori I never really had any problems except at this level with opencv-contrib ( it was good with opencv ).
