SyntheticGenV5

SyntheticGenV5 is a synthetic remote-sensing semantic segmentation dataset (from the paper https://huggingface.co/papers/2602.04749) built for Urban–Rural domain-aware learning.

It keeps the original folder layout and uses Train/metadata.csv to connect each image with its semantic mask and RGB mask.

Why use this dataset?

• 🌆 Two domains: Urban and Rural
• 🛰️ Designed for remote-sensing semantic segmentation
• 🧪 Useful for synthetic augmentation and domain generalization
• 👀 Includes RGB mask visualizations for easy inspection

Structure

Train/
├── metadata.csv
├── Urban/
│   ├── image_png/
│   ├── mask_png/
│   └── mask_rgb_png/
└── Rural/
    ├── image_png/
    ├── mask_png/
    └── mask_rgb_png/

Metadata Fields

Each row in Train/metadata.csv contains:

• image_file_name
• mask_file_name
• mask_rgb_file_name
• domain
• source_dataset

Load the dataset

from datasets import load_dataset

ds = load_dataset("buddhi19/SyntheticGenV5")
print(ds["train"][0])

Source

This dataset is derived based on LoveDA

Your downstream segmentation would work way better if you couple this dataset with original LoveDA dataset ;)

Notes

• The original directory layout is preserved.
• Train/metadata.csv is used for cleaner loading on Hugging Face.
• RGB masks are included mainly for visualization.
• This release currently contains the train split.
