BBS-Net: RGB-D Salient Object Detection with a Bifurcated Backbone Strategy Network

Figure 1: Pipeline of the BBS-Net.

1. Requirements

Python 3.7, Pytorch 0.4.0+, Cuda 10.0, TensorboardX 2.0, opencv-python

2. Data Preparation

• Download the raw data from Here [code: yiy1] and trained model (BBSNet.pth) from Here [code: dwcp]. Then put them under the following directory:

   -BBS_dataset\ 
     -RGBD_for_train\  
     -RGBD_for_test\
     -test_in_train\
   -BBSNet
     -models\
     -model_pths\
        -BBSNet.pth
     ...
  

• Note that the depth maps of the raw data above are not normalized. If you train and test using the normalized depth maps, the performance will be improved.

3. Training & Testing

• Train the BBSNet:

  python BBSNet_train.py --batchsize 10 --gpu_id 0

• Test the BBSNet:

  python BBSNet_test.py --gpu_id 0

  The test maps will be saved to './test_maps/'.

• Evaluate the result maps:

  You can evaluate the result maps using the tool in here.
