This codebase implemented training code for Space Time Memory Network with some cyclic features.

• We have post a journal version of our paper here, the modified cycle version of AOT model in our journal paper is also available now.

• torch
• python-opencv
• pillow
• yaml
• imgaug
• yacs
• progress
• nvidia-dali (optional)

• GPU Memory >= 12GB
• CUDA >= 10.0

See the doc DATASET.md for more details on data organization of our prepared dataset.

We provide pre-trained model with different backbone in our codebase, results are validated on DAVIS17-val with gradient correction.

Appending the root folder to the search path of python interpreter

export PYTHONPATH=${PYTHONPATH}:./

To train the STM network, run following command.

python3 train.py --cfg config.yaml OPTION_KEY OPTION_VAL

To test the STM network, run following command

python3 test.py --cfg config.yaml initial ${PATH_TO_MODEL} OPTION_KEY OPTION_VAL

The test results will be saved as indexed png file at ${ROOT}/${output_dir}/${valset}.

To run a segmentation demo, run following command

python3 demo/demo.py --cfg demo/demo.yaml OPTION_KEY OPTION_VAL

The segmentation results will be saved at ${output_dir}.

This codebase borrows the code and structure from official STM repository

The codebase is built based on following works
