I can't use opencv extra modules like Eigenfaces, Fisherfaces etc

Hello, I’m trying to use opencv with the npm package opencv4nodejs, the installation process works fine but the problem is when I try to use some extra module of opencv like eigenfaces and fisherfaces.

When I try to use theses modules an error shows to me saying EigenFaceRecognizer is not a valid constructor, I don’t believe the error is with the npm package because de install works well.

When I use the cmake to install theses extra modules the eigen is not intalled, someone know what can I do?

The nodejs code.

those functions are from the face module from the opencv-contrib repository and the build you have doesn’t contain contrib

hello @crackwitz I have this face module inside my opencv build folder.

try if cv.face.EigenFaceRecognizer exists? some of those functions might be namespaced.

support for the js face module is still in the making

When I log the cv.modules gives me that, and if I try to log cv.face gives me undefined, maybe I need to add the face module, but how can I do that, it’s not a default module of opencv?
