A Bangkit 2021 Capstone Project
Kestrel is a TensorFlow powered American Sign Language fingerspelling translator Android app that serves as a convenient way to learn and understand fingerspelling signs. The Kestrel model builds upon the state of the art MobileNetV2 model that is optimized for speed and latency on mobile devices to accurately recognize and interpret sign language from the phone’s camera with a 96.8% testing accuracy (99.60% training accuracy, 98.66% validation accuracy) and display its translation through a beautiful, convenient and easily accessible Android app.
Kestrel is now a part of my thesis research. The app is updated with:
- A brand new simplified user interface that instantly shows the viewfinder's live view and the top 5 fingerspelling results.
- A new MobileNetV2 model trained on a new dataset (Barczak et al., 2011), with 50% more detection categories (36 labels containing 26 alphabets and ten numbers).

The Kestrel model (95.2% testing accuracy, 98.16% training accuracy and 95.3% validation accuracy) is trained on 65.574 color images (comprising 24 static alphabet signs) from the American Sign Language FingerSpelling Dataset published by Nicolas Pugeault and Richard Bowden on the 2011 IEEE International Conference on Computer Vision Workshops.
