Distributional Instance Segmentation: Modeling Uncertainty and High Confidence Predictions with Latent-MaskRCNN

no code implementations3 May 2023 Yuxuan Liu, Nikhil Mishra, Pieter Abbeel, Xi Chen

Existing state-of-the-art methods are often unable to capture meaningful uncertainty in challenging or ambiguous scenes, and as such can cause critical errors in high-performance applications.
