Here is another app that lets you experiment with machine learning and computer vision on your phone. Neural Vision comes bundled with YOLOv3. It lets you import custom machine learning models for object detection and image classification. Users can change resolution and enable CPU only mode in the app.
Neural Vision draws a rectangle over detected objects and annotates them. It comes bundled with the Resnet50 image classification model. The models used are all open source and readily available on GitHub.
