Qualitative Comparisons Against SOTAs

Quantitative Comparisons Against SOTAs

6. Run Our Code

(1) Clone this repo

git clone https://github.com/xuebinqin/DIS.git

(2) Configuring the environment: go to the root DIS folder and run

conda env create -f pytorch18.yml

Or you can check the requirements.txt to configure the dependancies.

(3) Train:

(a) Open train_valid_inference_main.py, set the path of your to-be-inferenced train_datasets and valid_datasets, e.g., valid_datasets=[dataset_vd]
(b) Set the hypar["mode"] to "train"
(c) Create a new folder your_model_weights in the directory saved_models and set it as the hypar["model_path"] ="../saved_models/your_model_weights" and make sure hypar["valid_out_dir"](line 668) is set to "", otherwise the prediction maps of the validation stage will be saved to that directory, which will slow the training speed down
(d) Run

python train_valid_inference_main.py

(4) Inference

(a). Download the pre-trained weights (for fair academic comparisons only, the optimized model for engineering or common use will be released soon) isnet.pth from (Google Drive) or (Baidu Pan 提取码：xbfk) and store isnet.pth in saved_models/IS-Net
(b) Open train_valid_inference_main.py, set the path of your to-be-inferenced valid_datasets, e.g., valid_datasets=[dataset_te1, dataset_te2, dataset_te3, dataset_te4]
(c) Set the hypar["mode"] to "valid"
(d) Set the output directory of your predicted maps, e.g., hypar["valid_out_dir"] = "../DIS5K-Results-test"
(e) Run

python train_valid_inference_main.py

(5) Use of our Human Correction Efforts(HCE) metric

Set the ground truth directory gt_root and the prediction directory pred_root. To reduce the time costs for computing HCE, the skeletion of the DIS5K dataset can be pre-computed and stored in gt_ske_root. If gt_ske_root="", the HCE code will compute the skeleton online which usually takes a lot for time for large size ground truth. Then, run python hce_metric_main.py. Other metrics are evaluated based on the SOCToolbox.

7. Term of Use

Our code and evaluation metric use Apache License 2.0. The Terms of use for our DIS5K dataset is provided as DIS5K-Dataset-Terms-of-Use.pdf.
