Consider newer SSD Mobilenet model versions

I see the current version only allows ssdMobilenetv1 but seems like v2 is already available.

How hard is to get to use the newer version instead? Also, what’s needed to make it work on this project as a new model?

Edit: I’ve seen some v3 (here) but I don’t know how stable it is.

In the course of the last couple of months I have been working hard on getting better and faster face detectors to face-api.js. SSD in fact is not the best method for face detection anymore, FPNs (feature pyramid networks) are achieving state of the art results nowadays.

I am trying out different backbones for that purpose, mobilenetv3 is one of them. I have not decided yet, which backbone to use, still have to do some evaluation.

I do not want to decide on any ETA yet, but the latest models I can come up with are much more lightweight and already achieve higher accuracy with way less parameters than the SSDMobilenetV1 currently provided by face-api.js. I want to make sure, that the new models are as close to state of the art performance, while being as small and lightweight as possible.

So the new model (maybe models) I will be releasing are going to deprecate the currently provided face detection models. That’s one of the reasons I do not want do rush things.

Any updates on this? No rush of course, just curious.

Still working on this, I finally got the first versions of some models, that I am quite satisfied with. But still a lot of work has to be done, since I want these models not only to detect faces but also regress 5 point facial landmarks at the same time for face alignment.

Unfortunately training such a model until convergence takes more than one to two weeks, which does slow down the entire process.
