PyTorch implementation of "MGANet & DCC2020 paper"

MGANet

PyTorch implementation of "MGANet & DCC2020 paper", and we have merged the code of these two methods.

• ArXiv
• Data Compression Conference (DCC2020)

Related work

• TCSVT- Enhanced version of MGANet

The proposed MGANet framework

The guided encoder-decoder subnet

Installation

The code was developed using Python 3.6 & PyTorch 0.4 & CUDA 8.0. There may be a problem related to software versions. To fix the problem, you may look at the implementation in MGANet files and replace the syntax to match the new PyTorch environment.

Code v1.0

Currently, we release our research code for testing. It should produce the same results as in the paper under LD and AI configurations and frame number 3.

Test

• Pretrained models can be downloaded from this link!

https://drive.google.com/drive/folders/1xROBCUHgIX-3zqKMSHwKFEK8udIEicl1?usp=sharing

• It would be very easy to understand the test function and test on your own data.
• An example of test usage is shown as follows:

python MGANet_test_AI37.py --gpu_id 1 --is_training False

Train and Data

• We will update the training code and database for TUs' partition of compressed video by HEVC for training and better reading after recent paper deadline.

Video Results

• Here we provide quality enhancement results of compressed video for 18 widely used sequences for visual and quantitative comparisons.
