C2-Matching for CUDA11

C2-Matching (CVPR2021) CUDA11 version

This repository is based on C2-Matching, I made some modifications to run on CUDA11(CUDA11.3 and CUDA 11.6 were tested to work) as follows:

• Replace all AT_CHECK with TORCH_CHECK in mmsr/models/archs/dcn/src/deform_conv_cuda.cpp
• Replace mmsr/models/archs/DCNv2/ with a new implementation DCNv2_latest
  • Add class DCN_sep_pre_multi_offset(DCNv2) in line 194 of dcn_v2.py, which came from line 187 ~ 253 of dcn_v2.py

Dependencies and Installation

The following two environments were tested to work:

• Ubuntu 20.04
• Python 3.8
• PyTorch 1.11.0
• CUDA 11.3

and

• Ubuntu 20.04
• Python 3.8
• PyTorch 1.13.1
• CUDA 11.6

1. Clone Repo

   git clone https://github.com/include5636/C2-Matching-CUDA11.git

2. Install mmcv

   pip install mmcv==0.4.4

3. Install MMSR and DCNv2

Overview

Dataset Preparation

• Train Set: CUFED Dataset
• Test Set: WR-SR Dataset, CUFED5 Dataset

Please refer to Datasets.md for pre-processing and more details.

Get Started

Pretrained Models

Downloading the pretrained models from this link and put them under experiments/pretrained_models folder.

Test

We provide quick test code with the pretrained model.

1. Modify the paths to dataset and pretrained model in the following yaml files for configuration.

   ./options/test/test_C2_matching.yml
   ./options/test/test_C2_matching_mse.yml

2. Run test code for models trained using GAN loss.

   python mmsr/test.py -opt "options/test/test_C2_matching.yml"

   Check out the results in ./results.

3. Run test code for models trained using only reconstruction loss.

   python mmsr/test.py -opt "options/test/test_C2_matching_mse.yml"

   Check out the results in in ./results

Train

All logging files in the training process, e.g., log message, checkpoints, and snapshots, will be saved to ./experiments and ./tb_logger directory.

1. Modify the paths to dataset in the following yaml files for configuration.

   ./options/train/stage1_teacher_contras_network.yml
   ./options/train/stage2_student_contras_network.yml
   ./options/train/stage3_restoration_gan.yml

2. Stage 1: Train teacher contrastive network.

   python mmsr/train.py -opt "options/train/stage1_teacher_contras_network.yml"

3. Stage 2: Train student contrastive network.

   # add the path to *pretrain_model_teacher* in the following yaml
   # the path to *pretrain_model_teacher* is the model obtained in stage1
   ./options/train/stage2_student_contras_network.yml
   python mmsr/train.py -opt "options/train/stage2_student_contras_network.yml"

4. Stage 3: Train restoration network.

   # add the path to *pretrain_model_feature_extractor* in the following yaml
   # the path to *pretrain_model_feature_extractor* is the model obtained in stage2
   ./options/train/stage3_restoration_gan.yml
   python mmsr/train.py -opt "options/train/stage3_restoration_gan.yml"
   
   # if you wish to train the restoration network with only mse loss
   # prepare the dataset path and pretrained model path in the following yaml
   ./options/train/stage3_restoration_mse.yml
   python mmsr/train.py -opt "options/train/stage3_restoration_mse.yml"

Visual Results

For more results on the benchmarks, you can directly download our C2-Matching results from here.

Webly-Reference SR Dataset

Check out our Webly-Reference (WR-SR) SR Dataset through this link! We also provide the baseline results for a quick comparison in this link.

Webly-Reference SR dataset is a test dataset for evaluating Ref-SR methods. It has the following advantages:

• Collected in a more realistic way: Reference images are searched using Google Image.
• More diverse than previous datasets.
