There are three kinds of datasets: training dataset, validation dataset, and testing dataset. Usually, we do not explicitly distinguish between the validation and testing datasets in image/video restoration. So we use the validation/testing dataset in our description. <br/>
|
||||
We recommend to use [LMDB](https://lmdb.readthedocs.io/en/release/) (Lightning Memory-Mapped Database) formats for the training datasets, and directly read images (using image folder) during validation/testing. So there is no need to prepare LMDB files for evaluation/testing datasets.
|
||||
|
||||
---
|
||||
We organize the training datasets in LMDB format for **faster training IO speed**. If you do not want to use LMDB, you can also use the **image folder**.<br/>
|
||||
Besides the standard LMDB folder, we add an extra `meta_info.pkl` file to record the **meta information** of the dataset, such as the dataset name, keys and resolution of each image in the dataset.
|
||||
|
||||
Take the DIV2K dataset in LMDB for example, the folder structure and meta information are as follows:
|
||||
#### folder structure
|
||||
```
|
||||
- DIV2K800_sub.lmdb
|
||||
|--- data.mdb
|
||||
|--- lock.mdb
|
||||
|--- meta_info.pkl
|
||||
```
|
||||
#### meta information in `meta_info.pkl`
|
||||
`meta_info.pkl` is a python-pickled dict.
|
||||
|
||||
| Key | Value |
|
||||
|:----------:|:---------------------------------------------------------:|
|
||||
| name | `DIV2K800_sub_GT` |
|
||||
| keys | [ `0001_s001`, `0001_s002`, ..., `0800_s040` ] |
|
||||
| resolution | [ `3_480_480` ] |
|
||||
|
||||
If all the images in the LMDB file have the same resolution, only one copy of `resolution` is stored. Otherwise, each key has its corresponding `resolution`.

||||

|
||||
|
||||
The following shows how to prepare the datasets in detail.<br/>
|
||||
It is recommended to symlink the dataset root to $MMSR/datasets. If your folder structure is different, you may need to change the corresponding paths in config files.
|
||||
|
||||
## Prepare DIV2K
|
||||
[DIV2K](https://data.vision.ee.ethz.ch/cvl/DIV2K/) is a widely-used dataset in image super-resolution. In many research works, a MATLAB bicubic downsampling kernel is assumed. It may not be practical because the MATLAB bicubic downsampling kernel is not a good approximation for the implicit degradation kernels in real-world scenarios. And there is another topic named **blind restoration** that deals with this gap.
|
||||
|
||||
We provide a demo script for DIV2K X4 datasets preparation.
|
||||
```
|
||||
cd codes/data_scripts
|
||||
bash prepare_DIV2K_x4_dataset.sh
|
||||
```
|
||||
The specific steps are as follows:
|
||||
|
||||
**Step 1**: Download the GT images and corresponding LR images from the [official DIV2K website](https://data.vision.ee.ethz.ch/cvl/DIV2K/).<br/>
|
||||
Here are shortcuts for the download links:

|
||||
|
||||
**Step 2**: Rename the downloaded LR images to have the same name as those of GT.<br/> Run the script `data_scripts/rename.py`. Remember to modify the folder path.
|
||||
|
||||
**Step 3 (optional)**: Generate low-resolution counterparts. <br/>If you have downloaded the LR datasets, skip this step. Otherwise, you can use the script `data_scripts/generate_mod_LR_bic.m` or `data_scripts/generate_mod_LR_bic.py` to generate LR images. Make sure the LR and GT pairs have the same name.
|
||||
|
||||
**Step 4**: Crop to sub-images. <br/>DIV2K has 2K resolution (e.g., 2048 × 1080) images but the training patches are usually very small (e.g., 128x128). So there is a waste if reading the whole image but only using a very small part of it. In order to accelerate the IO speed during training, we crop the 2K resolution images to sub-images (here, we crop to 480x480 sub-images). You can skip this step if your have a high IO speed.<br/>
|
||||
Note that the size of sub-images is different from the training patch size (`GT_size`) defined in the config file. Specifically, the sub-images with 480x480 are stored in the LMDB files. The dataloader will further randomly crop the sub-images to `GT_size x GT_size` patches for training. <br/>
|
||||
Use the script `data_scripts/extract_subimages.py` with `mode = 'pair'`. Remember to modify the following configurations if you have different settings:
|
||||
```
|
||||
GT_folder = '../../datasets/DIV2K/DIV2K800'
|
||||
LR_folder = '../../datasets/DIV2K/DIV2K800_bicLRx4'
|
||||
save_GT_folder = '../../datasets/DIV2K/DIV2K800_sub'
|
||||
save_LR_folder = '../../datasets/DIV2K/DIV2K800_sub_bicLRx4'
|
||||
scale_ratio = 4
|
||||
```
|
||||
**Step 5**: Create LMDB files. <br/>You need to run the script `data_scripts/create_lmdb.py` separately for GT and LR images.<br/>
|
||||
|
||||
**Step 6**: Test the dataloader with the script `data_scripts/test_dataloader.py`.
|
||||
|
||||
This procedure is also applied to other datasets, such as 291 images, or your custom datasets.

Download the [`Septuplets dataset --> The original training + test set (82GB)`](http://data.csail.mit.edu/tofu/dataset/vimeo_septuplet.zip). This is the Ground-Truth (GT). There is a `sep_trainlist.txt` file recording the training samples in the download zip file.
|
||||
|
||||
**Step 2**: Generate the low-resolution images<br/>
|
||||
The low-resolution images in the Vimeo90K test dataset are generated with the MATLAB bicubic downsampling kernel. Use the script `data_scripts/generate_LR_Vimeo90K.m` (run in MATLAB) to generate the low-resolution images.
|
||||
|
||||
**Step 3**: Create LMDB files<br/>
|
||||
Use the script `data_scripts/create_lmdb.py` to generate the lmdb files separately for GT and LR images. You need to modify the configurations in the script:
|
||||
1) For GT
|
||||
```
|
||||
dataset = 'vimeo90K'
|
||||
mode = 'GT'
|
||||
```
|
||||
2) For LR
|
||||
```
|
||||
dataset = 'vimeo90K'
|
||||
mode = 'LR'
|
||||
```
|
||||
|
||||
**Step 4**: Test the dataloader with the script `data_scripts/test_dataloader.py`.
|
||||
|
||||

## Prepare REDS
|
||||
We re-group the REDS training and validation sets as follows:
|
||||
|
||||
| name | from | total number |
|
||||
|:----------:|:----------:|:----------:|
|
||||
| REDS training | the original training (except 4 clips) and validation sets | 266 clips |
|
||||
| REDS4 testing | 000, 011, 015 and 020 clips from the *original training set* | 4 clips |
|
||||
|
||||
The description of the REDS dataset can be found in [Open-VideoRestoration](https://xinntao.github.io/open-videorestoration/rst_src/datasets_sr.html#reds) and the [official website](https://seungjunnah.github.io/Datasets/reds.html).
|
||||
|
||||
**Step 1**: Download the datasets<br/>
|
||||
You can download the REDS datasets from the [official website](https://seungjunnah.github.io/Datasets/reds.html). The download links are also sorted as follows:
|
||||
|
||||
| track | links (training) | links (validation)|links (testing)|

|
||||
|
||||
**Step 2**: Re-group the datasets<br/>
|
||||
We rename the clips in the original validation set, starting from 240 ... It can be accomplished by `data_scripts/regroup_REDS.py`.
|
||||
Note that the REDS4 will be excluded in the data loader, so there is no need to remove the REDS4 explicitly.
|
||||
|
||||
**Step 3**: Create LMDB files<br/>
|
||||
Use the script `data_scripts/create_lmdb.py` to generate the lmdb files separately for GT and LR frames. You need to modify the configurations in the script:
|
||||
1) For GT (train_sharp)
|
||||
```
|
||||
dataset = 'REDS'
|
||||
mode = 'train_sharp'
|
||||
```
|
||||
2) For LR (train_sharp_bicubic)
|
||||
```
|
||||
dataset = 'REDS'
|
||||
mode = 'train_sharp_bicubic'
|
||||
```
|
||||
**Step 4**: Test the dataloader with the script `data_scripts/test_dataloader.py`.
|
||||
|
||||
