ssdkeras package - Under Construction, use at your own risk

This is a R port to Pierluigi Ferrari's Python implementation of Single Shot Multibox Detector - SSD.

See how to use it for detecting eyes, nose and mouth on the LFW faces dataset in this blog post.

Or get the gist with train_ssd7_faces.R with the data zipped at lfw_faces_tagged.zip.

You should get quite good results, e.g.:

As said this is under construction though working at large. Only lightly tested on my Windows machine in which for example Python, Keras, Tensorflow are already installed. Other packages needed:

tidyverse, stringr, reticulate, magick
