| # Mega Liminal |
|
|
| 1,873 captioned images of liminal spaces: empty malls, fog-bound roads, parking garages, suburbs at night, |
| vacant theatres and hallways, sorted into 10 classes and curated for training image models. The |
| [Mega Liminal LoRA](https://huggingface.co/AbstractPhil/mega-liminal-lora) was trained on it. |
|
|
| ## Contents |
|
|
| | Class | Files | |
| |---|---| |
| | mega liminal | 870 | |
| | landscape | 766 | |
| | suburban | 111 | |
| | simulacrum | 36 | |
| | vanishing point | 21 | |
| | empty mall | 20 | |
| | hand sourced | 18 | |
| | parking garage | 13 | |
| | cityscape | 10 | |
| | movie theatre | 8 | |
| | **total** | **1,873 files, 1,060 unique images** | |
|
|
| The classes overlap. The mega liminal class gathers most of the landscape images and some suburban ones, |
| so 813 files are byte-identical copies filed under a second class. Each copy has its own caption. The |
| `also_in` column names the other copies; keep one row per `sha256` for a deduplicated set. |
|
|
| The captioner labeled 1,680 images as photographs, 122 as 3D renders, 69 as digital paintings and 2 as |
| drawings. 55 images carry a visible watermark (`watermark` column). |
|
|
| ## Layout |
|
|
| ``` |
| data/<class>/<image> the image (jpg, jpeg, png or webp) |
| data/<class>/<image stem>.txt its caption |
| data/metadata.jsonl one row per image: file_name, text, class, width, height, medium, watermark, sha256, also_in |
| omitted_manifest.csv the 202 source images removed during curation, with the reason |
| ``` |
|
|
| ## Loading |
|
|
| With the `datasets` library: |
|
|
| ```python |
| from datasets import load_dataset |
| ds = load_dataset("AbstractPhil/mega-liminal", split="train") |
| ``` |
|
|
| For trainers that read image and `.txt` pairs (kohya, ai-toolkit, diffusion-pipe, OneTrainer), download the |
| files and point the trainer at `mega-liminal/data/<class>`: |
|
|
| ```bash |
| hf download AbstractPhil/mega-liminal --repo-type dataset --local-dir mega-liminal |
| ``` |
|
|
| ## Captions |
|
|
| Every caption has the form `liminal, <class>, <description>`. Qwen3.5-9B wrote the descriptions, one |
| structured pass per image: two to four sentences covering the kind of image, the place and its layout, |
| the camera position, the architecture and materials, and the lighting and colors. The prompt ruled out |
| mood words and sentences about what is absent, and a cleanup pass removed any that slipped through. Some |
| captions mention visible text or a watermark. |
|
|
| ## Curation |
|
|
| 202 of the 2,075 source images were removed: |
|
|
| | Reason | Images | |
| |---|---| |
| | under 512x512 pixels (262,144) | 63 | |
| | video-game screenshots (Garry's Mod and similar engines) | 74 | |
| | low-resolution 3D render | 33 | |
| | cartoon or toy render | 17 | |
| | low-poly or untextured 3D | 10 | |
| | pixel art | 3 | |
| | framed collage | 2 | |
|
|
| Every removal except the pixel-count rule was checked by eye. Clean, high-resolution renders were kept. |
|
|
| ## Licensing |
|
|
| The images were gathered from public liminal-space collections on the web. Their rights stay with their |
| original creators, and some carry the creator's watermark. The dataset is shared for research and |
| non-commercial use. To have an image removed, open a discussion on this repo. |
|
|
| The captions were written by Qwen3.5-9B for this dataset. |
