VectorSynth: Fine-Grained Satellite Image Synthesis with Structured Semantics

This repository is the official implementation of VectorSynth. VectorSynth is a suite of models for synthesizing satellite images with global style and text-driven layout control.

🤗 Models

VectorSynth:

VectorSynth-COSA:

🌏 Inference

from diffusers import StableDiffusionControlNetPipeline
pipe = StableDiffusionControlNetPipeline.from_pretrained("MVRL/VectorSynth")

See inference.py for a complete example with hint processing.

🔬 COSA

For using COSA, see cosa/README.md.

🧑‍💻 Setup and Training

Create a conda environment:

conda env create -f environment.yaml
conda activate vectorsynth

The dataset can be downloaded from here. See dataset.md for generating your own data from OpenStreetMap.

See train.md for training details.
