Pre-trained Model

We provide pre-trained ICNet based on SISMs produced by pre-trained EGNet (VGG16-based).

• ICNet_vgg16.pth (70MB), GoogleDrive | BaiduYun (fetch code: nkj9).

Prediction Results

We release the co-saliency maps (predictions) generated by our ICNet on 5 benchmark datasets:

MSRC, iCoseg, Cosal2015, CoCA, and CoSOD3k.

• cosal-maps.zip (results of size 224*224, 20MB), GoogleDrive | BaiduYun (fetch code: du5e).

• cosal-maps-os.zip (results resized to original sizes, 62MB), GoogleDrive | BaiduYun (fetch code: xwcv).

Training and Test

Prepare SISMs

Our ICNet can be trained and tested based on SISMs produced by any off-the-shelf SOD method, but you are suggested to use the same SOD method to generate SISMs in training and test phases to keep the consistency.

In our paper, we choose the pre-trained EGNet (VGG16-based) as the basic SOD method to produce SISMs, you can downloaded these SISMs directly from:

• EGNet-SISMs (resized to 224*224, 125MB), GoogleDrive | BaiduYun (fetch code: ae6a).

Training

1. Download pre-trained VGG16 from:

   • vgg16_feat.pth (56MB), GoogleDrive | BaiduYun (fetch code: j0zq).

2. Follow instructions in "./ICNet/train.py" to modify training settings.

3. Run:

python ./ICNet/train.py

Test

1. • Test pre-trained ICNet:

     Download pre-trained ICNet "ICNet_vgg16.pth" (the download link is given above).

   • Test ICNet trained by yourself:

     Choose the checkpoint file "Weights_i.pth" (saved after i-th epoch automatically) you want to load for test.

2. Follow instructions in "./ICNet/test.py" to modify test settings.

3. Run:

python ./ICNet/test.py

Evaluation

The folder "./ICNet/evaluator/" contains evaluation codes implemented in PyTorch (GPU-version), the metrics include max F-measure, S-measure, and MAE.

1. Follow instructions in "./ICNet/evaluate.py" to modify evaluation settings.

2. Run:

python ./ICNet/evaluate.py

Compared Methods

We compare our ICNet with 7 state-of-the-art Co-SOD methods:

• CBCS ''Cluster-Based Co-Saliency Detection, TIP(2013)''​

• CSHS ''Co-Saliency Detection Based on Hierarchical Segmentation, SPL(2014)''

• CoDW ''Detection of Co-salient Objects by Looking Deep and Wide, IJCV(2016)''

• UCSG ''Unsupervised CNN-based Co-Saliency Detection with Graphical Optimization, ECCV(2018)''

• CSMG ''Co-saliency Detection via Mask-guided Fully Convolutional Networks with Multi-scale Label Smoothing, CVPR(2019)''

• MGLCN ''A Unified Multiple Graph Learning and Convolutional Network Model for Co-saliency Estimation, ACM MM(2019)''

• GICD ''Gradient-Induced Co-Saliency Detection, ECCV(2020)''

You can download predictions of these methods from:

• compared_methods (original sizes, 445MB), GoogleDrive | BaiduYun (fetch code: s7pr).
