I would like to do face detection &amp; recognition using KotlinDL.

As far as I understand I will need <https://github.com/onnx/models/tree/main/vision/body_analysis/arcface|ArcFace> for Face Recognition and as a preprocessing detect the faces first.

Therefore I'm looking for a MTCNN face detector for Kotlin. At best it's an implementation that does not require a Bitmap or other like Android-specific classes and just takes a JPG stream to detect the coordinates. I want to use it on the JVM within a compose-jb app.

Does someone know something like that?

<https://github.com/tzolov/mtcnn-java> is the closest thing I found so far, but it's abandoned and seems to have a lot of depenencies.

Is there something easier to use for that?

We have a face detection API for KotlinDL ONNX (<https://github.com/Kotlin/kotlindl/blob/master/examples/src/main/kotlin/examples/onnx/faces/FaceDetectionWithVisualization.kt>). This version is not yet been released, but you can try to build it from the source.
