Rotating Features for Object Discovery

Our proposed Rotating Features learn to represent object affiliation via their orientation on real-world data without labels. We achieve this by extending standard features by an extra dimension across the entire architecture. We then set up the layer structure in such a way that the Rotating Features’ magnitudes learn to represent the presence of features, while their orientations learn to represent object affiliation. This allows us to achieve strong object discovery performance on real-world images in an unsupervised way.

Setup

• Install conda
• Adjust the setup_environment.sh script to your needs (e.g. by setting the right CUDA version)
• Run the setup script:

bash setup_environment.sh

• Run the download script to download the 4Shapes datasets, FoodSeg103 and Pascal VOC 2012:

bash download_data.sh

Run Experiments

• Train and evaluate an autoencoding model with Rotating Features on the provided datasets:

source activate RotatingFeatures
python -m codebase.main +experiment=4Shapes

python -m codebase.main +experiment=4Shapes_RGBD

python -m codebase.main +experiment=FoodSeg

python -m codebase.main +experiment=Pascal
