DPANet:Depth Potentiality-Aware Gated Attention Network for RGB-D Salient Object Detection (paper) (project) (talk)

This repo. is an official implementation of the DPANet , which has been published on the journal IEEE Transactions on Image Processing, 2021.

The main pipeline is shown as the following,

And some visualization results are listed

Dependencies

>= Pytorch 1.0.0
OpenCV-Python
[optional] matlab

Preparation

• download the official pretrained model of ResNet-50/ResNet-34/ResNet-18 implemented in Pytorch if you want to train the network again.
• download or put the RGB-D saliency benchmark datasets (Google drive) in the folder of data for training or test.
• [optional] generate the pseudo label (provided for NJUD and NLPR) using the scripts gen.m and cal_score.py.

Training

python3 train.py --tag res50 --save_path res50_res

make sure that the GPU memory is enough (the original training is conducted on 8 NVIDIA RTX2080Ti cards with the batch size of 32).

Test

 python3 test.py --tag res50 --gpu 0 --model res50_res/model-30

We provide the trained model file (Google drive), and run this command to check its integrity:

md5sum model-res50-epoch30.pt 

you will obtain the code b666d297e0237035f6e48f80711ca927. Please use the matlab code to evaluate the MAE, F-measure, or other metrics rather than using the accuracy defined in the test.py.

The saliency maps are also available (Google drive).

Evaluation

We provide the evaluation code in the folder "eval_code" for fair comparisons. You may need to revise the algorithms , prepath, and maskpath defined in the main.m. The saliency maps of the competitors (official maps or obtained by running the official code) are provided (Google drive).
