  1. This work is based on MATLAB;
  2. Before use this code, please download the VGG16 network pretrained on ImageNet, imagenet-vgg-verydeep-16.mat, and put it under a subfolder /data
  3. FR_DeepSim.m is the main function;
  4. FR_DeepSim_demo.m is an example, imageDis.bmp is a distorted image, and imageRef.bmp is the corresponding refernce/undistorted image.
  5. pooling.m includes different pooling methods;
  6. CNN paractical.pdf introduces the matconvnet toolbox:;
