Abstract Recent deep learning based salient object detection methods achieve gratifying performance built upon Fully Convolutional Neural Networks (FCNs). However, most of them have suffered from the boundary challenge. The state-of-the-art methods employ feature aggregation technique and can precisely find out wherein the salient object, but they often fail to segment out the entire object with fine boundaries, especially those raised narrow stripes. So there is still a large room for improvement over the FCN based models. In this paper, we design the Attentive Feedback Modules (AFMs) to better explore the structure of objects. A Boundary-Enhanced Loss (BEL) is further employed for learning exquisite boundaries. Our proposed deep model produces satisfying results on the object boundaries and achieves state-of-the-art performance on five widely tested salient object detection benchmarks. The network is in a fully convolutional fashion running at a speed of 26 FPS and does not need any post-processing.

Usage

1. Clone this repo into your computer

   git clone https://github.com/ArcherFMY/AFNet.git

2. Cd to AFNet/caffe, follow the official instructions to build caffe. We provide our make file my-Makefile.config in folder AFNet/caffe.

The code has been tested successfully on Ubuntu 14.04 with CUDA 8.0 and OpenCV 3.1.0

3. Make caffe & matcaffe

   make all -j
   make matcaffe -j

4. Download pretrained caffemodel from [google drive] or [baidu yun] (Fetch Code: sifm) and extract the .zip file under the root directory AFNet/.

5. Put the test image in AFNet/test-Image/ and run test_AFNet.m to get the saliency maps. The results will be saved in AFNet/results/AFNet/
