Keypoint Detection

This repository contains examples and best practice guidelines for building keypoint detection systems. It also shows how to use a pre-trained model for human pose estimation.

Keypoints are defined as points-of-interests on objects. For example, one might be interested in finding the position of the lid on a bottle. Another example is to find body joints (hands, shoulders, etc.) for human pose estimation.

We use an extension of Mask R-CNN which simultaneously detects objects and their keypoints. The underlying technology is very similar to our approach for object detection, ie. based on Torchvision's Mask R-CNN. The example notebook for keypoint localization is therefore in the detection folder.
