Teeth detector

⚠️ Dataset is private at the moment. For privacy reasons it can't be shared. We are trying to get approval from hospitals and patients included in this dataset but this a work in progress. For the same privacy reasons the trained model can't be shared at the moment.

The dataset was made with a stomatologist surgeon using VoTT for labeling. The export was made under the Tensorflow Pascal VOC format

The project is divided into two tasks:

1. Detect tooth restoration, endodontic treatment and implants (models/treatment)
2. Detect teeth and identify their ISO Dental Notation (models/index)

Installation

• Download the datasets from the google drive (datasets are private at the moment)
• Install tensorflow object detection: https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md
• Install Cloud SDK to run on google cloud https://cloud.google.com/sdk/

pip install -r requirements.txt
