SpatialEmbedding: Instance Segmentation by Jointly Optimizing Spatial Embeddings and Clustering Bandwidth

July 2020

tl;dr: Single stage instance segmentation with bottom-up approach.

Overall impression

Overall performance is not that great compared to other approaches. This forms the foundation of PointTrack.

PointTrack uses a single stage instance segmentation method with a seeding location. This makes it compatible with many instance segmentation method, such as CenterMask or BlendMask.

The visualization of instance distance map looks great.
