Semantic Instance Segmentation
- Proposal-based solutions: - Hundreds/Thousands of redundant predictions- Post-processing needed (NMS)
- Holistic & class-agnostic methods- Reduced set of predictions- Separate network for semantics
Motivation

- Our solution: - Recurrent model that sequentially predicts binary masks and
categorical labels for each object in an image.- Learns to stop once all objects have been found.- Does not need post-processing on its output.
