Requirements

This work was implemented with the following frameworks:

• Spyder 3.2.x (recommended)
• Python 3.6.3
• Keras 2.0.6
• Tensorflow-gpu 1.1.0

Usage

1. Clone this repo: git clone https://github.com/lim-anggun/FgSegNet_v2.git

2. Download CDnet2014, SBI2015 and UCSD datasets, then put them in the following directory structure:
   

   Example:

    FgSegNet_v2/
         scripts/FgSegNet_v2_CDnet.py
                /FgSegNet_v2_SBI.py
                /FgSegNet_v2_UCSD.py
                /FgSegNet_v2_module.py
                /instance_normalization.py
                /my_upsampling_2d.py
         datasets/
                 /CDnet2014_dataset/...
                 /SBI2015_dataset/...
                 /UCSD_dataset/...
         training_sets/
                      /CDnet2014_train/...
                      /SBI2015_train/...
                      /UCSD_train20/...
                      /UCSD_train50/...
   

3. Run the codes with Spyder IDE. Note that all trained models will be automatically saved (in current working directory) for you.

Evaluation

We evaluate our method using three different datasets as described in here or here.
