Unsupervised Multi-Object Segmentation by Predicting Probable Motion Patterns

NeurIPS 2022
pdfproject pagecodearXivBibTeX
We learn to segment independent objects in still images by predicting regions that contain motion patterns likely to arise from such objects.

Guess What Moves: Unsupervised Video and Image Segmentation by Anticipating Motion

BMVC 2022 (Spotlight)
pdfproject pagevideocodearXivBibTeX
We use motion anticipation as a learning signal to train an image segmentation network to predict regions that likely contain similar optical flow patterns

Unsupervised Part Discovery from Contrastive Reconstruction

NeurIPS 2021
pdfproject pagevideocodearXivBibTeX
Unsupervised discovery of semantically meaningful parts of objects using appearance consistency cues and contrastive learning

The Curious Layperson: Fine-Grained Image Recognition without Expert Labels

pdfproject pagevideocodearXivBibTeX
Proposes a new problem of fine-grained image classification without expert annotations, by utilizing class agnostic non-expert descriptions and off-the-shelf expert corpus

Semantic Projection Network for Zero- and Few-Label Semantic Segmentation

Yongqin Xian*, Subhabrata Choudhury*, Yang He, Bernt Schiele, Zeynep Akata
CVPR 2019
pdfproject pagecodeBibTeX
Extenstion of zero-shot learning to segmentation: perform dense labelling of 'unseen' test classes by training on mutually exclusive 'seen' training classes with additional help from side information
