SSAV framework

Abstract The last decade has witnessed a growing interest in video salient object detection (VSOD). However, the research community long-term lacked a well-established VSOD dataset representative of real dynamic scenes with high-quality annotations. To address this issue, we elaborately collected a visual-attention-consistent Densely Annotated VSOD (DAVSOD) dataset, which contains 226 videos with 23,938 frames that cover diverse realistic-scenes, objects, instances and motions. With corresponding real human eye-fixation data, we obtain precise ground-truths. This is the first work that explicitly emphasizes the challenge of saliency shift, i.e., the video salient object(s) may dynamically change. To further contribute the community a complete benchmark, we systematically assess 17 representative VSOD algorithms over seven existing VSOD datasets and our DAVSOD with totally ~84K frames (largest-scale). Utilizing three famous metrics, we then present a comprehensive and insightful performance analysis. Furthermore, we propose a baseline model. It is equipped with a saliencyshift-aware convLSTM, which can efficiently capture video saliency dynamics through learning human attention-shift behavior. Extensive experiments1 open up promising future directions for model development and comparison.

Usage

  1. Clone this repo into your computer
git clone https://github.com/DengPingFan/DAVSOD.git
  1. Cd to DAVSOD/mycaffe-convlstm, follow the official instructions to build caffe. We provide our make file Makefile.config in folder DAVSOD/mycaffe-convlstm.

The code has been tested successfully on Ubuntu 16.04 with CUDA 8.0 and OpenCV 3.1.0

  1. Make 'caffe'
make all -j8
  1. Make 'pycaffe'
make pycaffe

  1. Download pretrained caffemodel from my homepage or directly from [baidu pan](Fetch Code: pb0h)/ [google drive] and extract the .zip file under the root directory DAVSOD/model/. If you want to train the model start from scratch, you can download the basemodel from [baidu pan](Fetch Code:0xk4) or [google drive]

  2. Put the test image in DAVSOD/Datasets/ and run generateTestList.py to get the test list. Then run SSAV_test.py to get the saliency maps. The results will be saved in DAVSOD/results/SSAV/.

  3. You can also evaluate the model performance (S-measure[1], E-measure[2], F-measure and MAE) using our one-key matlab code main.m in DAVSOD/EvaluateTool/ directory.

Note that: This version only provide the implicit manner for learning attention-shift. The explicit way to train this model will not be released due to the commercial purposes (Hua Wei, IIAI).
