# Dronescapes dataset
As introduced in our ICCV 2023 workshop paper: [link](https://openaccess.thecvf.com/content/ICCV2023W/LIMIT/papers/Marcu_Self-Supervised_Hypergraphs_for_Learning_Multiple_World_Interpretations_ICCVW_2023_paper.pdf)
# 1. Downloading the data
## Option 1. Download the pre-processed dataset from HuggingFace repository
```
git lfs install # Make sure you have git-lfs installed (https://git-lfs.com)
git clone https://huggingface.co/datasets/Meehai/dronescapes
```
Note: the dataset has about 300GB, so it may take a while to clone it.
Option 2. Generating the dataset from raw videos and basic labels .
Recommended if you intend on understanding how the dataset was created or add new videos or representations.
### 1.2.1 Raw videos
Follow the commands in each directory under `raw_data/videos/*/commands.txt` if you want to start from the 4K videos.
If you only want the 540p videos as used in the paper, they are already provided in the `raw_data/videos/*` directories.
### 1.2.2 Semantic segmentation labels (human annotated)
These were human annotated and then propagated using [segprop](https://github.com/vlicaret/segprop).
```bash
cd raw_data/
tar -xzvf segprop_npz_540.tar.gz
```
### 1.2.3 Generate the rest of the representations
We use the [video-representations-extractor](https://gitlab.com/meehai/video-representations-extractor) to generate
the rest of the labels using pre-traing networks or algoritms.

### 1.2.4 Convert Mask2Former from Mapillary classes to segprop8 classes
Since we are using pre-trained Mask2Former which has either mapillary or COCO panoptic classes, we need to convert them to dronescapes-compatible (8) classes.
To do this, we use the `scripts/convert_m2f_to_dronescapes.py` script:
```
python scripts/convert_m2f_to_dronescapes.py in_dir out_dir mapillary/coco [--overwrite]
```
```

### 1.2.5 Check counts for consistency
Run: `bash scripts/count_npz.sh raw_data/npz_540p`. At this point it should return:
| scene | rgb | depth_dpt | depth_sfm_manual20.. | edges_dexined | normals_sfm_manual.. | opticalflow_rife | semantic_mask2form.. | semantic_segprop8 |

### 1.2.6. Split intro train, validation, semisupervised and train
We include 8 splits: 4 using only GT annotated semantic data and 4 using all available data (i.e. segproped between
annotated data). The indexes are taken from `txt_files/*`, i.e. `txt_files/manually_adnotated_files/test_files_116.txt`
refers to the fact that the (unseen at train time) test set (norway + petrova + barsana) contains 116 manually
annotated semantic files. We include all representations from above, not just semantic for all possible splits.
Adding new representations is as simple as running VRE on the 540p mp4 file

```
Note: `add --copy_files` if you want to make copies instead of using symlinks.
Upon calling this, you should be able to see something like this:
```

## 2. Using the data
As per the split from the paper:
The data is in `data/*` (see the `ls` call above, it should match even if you download from huggingface).
## 2.1 Using the provided viewer
Basic usage:
```
python scripts/dronescapes_viewer.py data/test_set_annotated_only/ # or any of the 8 directories in data/
```
Expected output
```
