This is the implementation of paper Hyperbolic Image Segmentation (CVPR 2022).
- assets : images and stuff
- datasets : contains integer to class dictionaries, and JSON files that contain the hierarchies used.
- hesp : the actual code containing layers, models, losses, etc.
- samples : helper files, bash scripts, and train.py
Code is not complete yet.
For installation, first run pip install -e . to register the package.
Then, run sh requirements.sh to install the requirements.
The code needs Tensorflow 1, the experiments are performed using Tensorflow 1.14. The tensorflow installed by the script is tensorflow-cpu. Change the commands to install tensorflow on GPU.
To train a model, use this code in samples directory.
python train.py --mode segmenter --batch_size 5 --dataset coco --geometry hyperbolic --dim 256 --c 0.1 --freeze_bn --train --test --backbone_init Path_to_resnet/resnet_v2_101_2017_04_14/resnet_v2_101.ckpt --output_stride 16 --segmenter_ident check
The code will train and test a hyperbolic model using coco stuff dataset, with batch size 5, curvature 0.1, freeze batch
normalization, output stride 16. The result will be saved in a folder named
poincare-hesp/save/segmenter/hierarchical_coco_d256_hyperbolic_c0.1_os16_resnet_v2_101_bs5_lr0.001_fbnTrue_fbbFalse_check in the samples directory.
