Arxiv


We present Zero-Painter , a novel training-free framework for layout-conditional text-to-image synthesis that facilitates the creation of detailed and controlled imagery from textual prompts. Our method utilizes object masks and individual descriptions, coupled with a global text prompt, to generate images with high fidelity. Zero-Painter employs a two-stage process involving our novel Prompt-Adjusted Cross-Attention (PACA) and Region-Grouped Cross-Attention (ReGCA) blocks, ensuring precise alignment of generated objects with textual prompts and mask shapes. Our extensive experiments demonstrate that Zero-Painter surpasses current state-of-the-art methods in preserving textual details and adhering to mask shapes.

🔥 News

  • [2024.06.6] ZeroPainter paper and code is released.
  • [2024.02.27] Paper is accepted to CVPR 2024.

⚒️ Installation

Install with pip:

pip3 install -r requirements.txt

💃 Inference: Generate images with Zero-Painter

  1. Download models and put them in the models folder.
  2. You can use the following script to perform inference on the given mask and prompts pair:
python zero_painter.py \
  --mask-path data/masks/1_rgb.png \
  --metadata data/metadata/1.json \
  --output-dir data/outputs/

meatadata sould be in the following format

[{
    "prompt": "Brown gift box beside red candle.",
    "color_context_dict": {
        "(244, 54, 32)": "Brown gift box",
        "(54, 245, 32)": "red candle"
    }
}]
