This is the official code for the paper Look here! A parametric learning based approach to redirect visual attention, to appear in ECCV 2020.

The pre-trained saliency model assumes the followed package versions:

python 3.5

tensorflow 1.13.1

keras 2.2.4

To avoid version mismatches, you could create a new environment via:

conda create --name <env> --file mdsem-env.txt

Once the environment created, install the rest of the packages via:

pip install -r pip_requirements.txt

1- Download COCO dataset if not already available.

2- Download the saliency model and extract the folder in your working directory. The model can be downloaded from: https://drive.google.com/file/d/1ILq7bm8D9dOnqP-kDr218703QXGaDmMG/view?usp=sharing

3- You can download pre-trained models for all training settings mentioned below via the google drive link: https://drive.google.com/drive/folders/1TT27mR-Wmf3mhHfbPGQluQZ30ukl_yp1?usp=sharing

Start by creating the CoCoClutter dataset by replacing with your paths in th commands below. Here it is assumed that COCO has been placed in ./datasets/COCO.

1- Create training data:

python create_dataset.py --path ./datasets/COCO --salmodelpath ./saliency-shared-dir/mdsem_model_LSUN_Oct2019/mdsem_model_LSUN_full.h5

2- Create validation data:

python create_dataset_val.py --path ./datasets/COCO --salmodelpath ./saliency-shared-dir/mdsem_model_LSUN_Oct2019/mdsem_model_LSUN_full.h5

These will create the folders ./datasets/CoCoClutter/increase/maskdir and ./datasets/CoCoClutter/increase/maskdir_val respectively.

python main.py --data ./datasets/CoCoClutter/increase --path ./datasets/datasets/COCO --salmodelpath ./saliency-shared-dir/mdsem_model_LSUN_Oct2019/mdsem_model_LSUN_full.h5

Checkpoints will be saved in the parent directory logs. Intermediate results can be visualized using tensorboard. Test results are computed directly after the training and are saved in the same directory as the corresponding checkpoint files.

Inference from pre-trained models, can be done using the command below (Here we use assume that the checkpoint files are stored in $checkpoint_dir):

python main.py --data ./datasets --path /home/yam28/Documents/phdYoop/datasets/datasets/COCO --salmodelpath ./saliency-shared-dir/mdsem_model_LSUN_Oct2019/mdsem_model_LSUN_full.h5 --checkpoint_dir $checkpoint_dir --traintest 2 --batch_size 1 --dataloader CoCoLoader_rectangle_HR

If you want to do inference on your own images. The best way is to use a frozen model. To do so, first freeze the model using:

python freeze_graph.py --model_dir $checkpoint_dir

The frozen graph is saved in the corresponding log directory under frozen_model.pb.

You can then run inference. We provide an inference example script using the small example_data provided in the datasets folder:

python infer_HR.py --frozen_model $checkpoint_dir/frozen_model.pb

Images will be saved under results_from_frozen in the corresponding checkpoint directory.

Using the frozen model, one can perfrom interactive image editing. An example is provided in `GUI.py':

python GUI.py --frozen_model $checkpoint_dir/frozen_model.pb

Important note: to use the GUI, please install the user interface library PySimpleGUI. You might need to switch to a python version >3.5 for this to work.

You can train the model to produce diverse outputs from the same image and mask by running the command below:

python main.py --data ./datasets/CoCoClutter/increase --path ./datasets/COCO --salmodelpath ./saliency-shared-dir/mdsem_model_LSUN_Oct2019/mdsem_model_LSUN_full.h5 --trainer adv_increase_multistyle_sftmx --G increase_multistyle 

Inference will be done automatically after training. However you can run inference from a pre-trained model in a similar manner as previously:

python main.py --data ./datasets/CoCoClutter/increase --path ./datasets/COCO --salmodelpath ./saliency-shared-dir/mdsem_model_LSUN_Oct2019/mdsem_model_LSUN_full.h5 --trainer adv_increase_multistyle_sftmx --G increase_multistyle --checkpoint_dir $checkpoint_dir --traintest 2 --batch_size 1 --dataloader CoCoLoader_rectangle_HR

You can train the model to shift the attention towards and away from the object. To do this, follow the steps below:

1- Create the dataset for this task (This is different from CoCoClutter):

Training data:

python create_dataset_incdec.py --path ./datasets/COCO --salmodelpath ./saliency-shared-dir/mdsem_model_LSUN_Oct2019/mdsem_model_LSUN_full.h5

Validation data:

python create_dataset_incdec_val.py --path ./datasets/COCO --salmodelpath ./saliency-shared-dir/mdsem_model_LSUN_Oct2019/mdsem_model_LSUN_full.h5

These will create the folders ./datasets/CoCoClutter/incdec/maskdir and ./datasets/CoCoClutter/incdec/maskdir_val respectively.

2- Train the model:

python main.py --data ./datasets/CoCoClutter/incdec --path ./datasets/COCO --salmodelpath ./saliency-shared-dir/mdsem_model_LSUN_Oct2019/mdsem_model_LSUN_full.h5 --G incdec --trainer adv_incdec_sftmx --batch_size 2 --LAMBDAsal 20000 --nb_its 300000

Inference will be done automatically after training. However you can run inference using a pre-trained model in a similar manner as previously:

python main.py --data ./datasets/CoCoClutter/incdec --path ./datasets/COCO --salmodelpath ./saliency-shared-dir/mdsem_model_LSUN_Oct2019/mdsem_model_LSUN_full.h5 --G incdec --trainer adv_incdec_sftmx --checkpoint_dir $checkpoint_dir --traintest 2 --batch_size 1 --dataloader CoCoLoader_rectangle_HR
