Cross Quality Distillation

Introduction

This repository contains the code for reproducing the results in "Adapting Models to Signal Degradation using Distillation", BMVC, 2017 (Originally with the title "Cross Quality Distillation" on arXiv)

}

Code is tested on Ubuntu 14.04 with MATLAB R2014b and MatConvNet package.
Link to the project page.
Code is borrowed heavily from B-CNN (https://bitbucket.org/tsungyu/bcnn).

Instruction

1. Follow instructions on VLFEAT and MatConvNet project pages to install them first. Our code is built on MatConvNet version 1.0-beta18.
2. Change the path in setup.m
3. Download datasets
   • Birds: CUB-200-2011 dataset.
   • Cars: Stanford cars dataset
4. Run save_images.m to create degraded images (Need to download and install Structured Edge Detector for generating edge images and tpsWarp for generating distorted images)
5. Download and put pre-trained vgg models under data/models/ (vgg-m and vgg-vd are used in the paper)
6. Run run_CQD.m for training all the baseline models and distillation model

Results

Please see Table 1 in the paper.
