| # 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 | |
| TODO: recommended | |
| <details> | |
| <summary> <b> Option 2. Generating the dataset from raw videos and basic labels </b>.</summary> | |
| 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 | |
| TODO | |
| ### 1.2.5 Check counts for consistency | |
| Run: `bash 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 | |
| ``` | |
| ./symlinks_from_txt_list.py raw_data/npz_540p/ --txt_file txt_files/annotated_and_segprop/train_files_11664.txt -o data/train_set --overwrite | |

| ``` | |
| 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: | |
| ``` | |
| ./dronescapes_viewer.py data/test_set_annotated_only/ # or any of the 8 directories | |
| ``` | |
