Instructions:

This code has been tested in Windows10-64bit with Python3.4 installed.  
1. clone this project and put all the files in the same folder
2. folder structure:

      FoHIS/const.py  # define const
            fog.py  # main
            parameter.py # all parameters used in simulating fog/haze are defined here.
            tool_kit.py # some useful functions
            
      AuthESI/compute_aggd.py
              compute_authenticity.py  # main
              guided_filter.py  # some functions
              prisparam_16_hazeandfog.mat  # pre-trained model
              
      img/img.jpg  # RGB image
          imgd.jpg  # depth image
          result.jpg  # simulation
          
3. To simulate fog/haze effects:
    run python FoHIS/fog.py, the output 'result.jpg' will be saved in ../img/
      
4. To evaluate the authenticity:
    run python compute_authenticity.py to evaluate 'result.jpg' in ../img/
