LuminaBrush
Lighting drawing tool for text to image diffusion model
0
- Two stage framework: First, convert the image into a uniformly illuminated appearance, and then generate lighting effects based on user input.
- • Support user graffiti: Users can use graffiti to guide the generation of lighting effects.
- Extract uniform illumination appearance from high-quality images: used for training illumination drawing models.
- • Independent use of uniform lighting stage: used to illuminate images and provide different visual effects.
- • Support Flux model: LuminaBrush is built on Flux and trained using Flux LoRA.
- • Provide Hugging Face Demo: Users can try the LuminaBrush demo on Hugging Face.
- Suitable for various images: capable of processing details such as skin texture, hair, fur, etc.
Product Details
LuminaBrush is an interactive tool designed to draw lighting effects on images. This tool adopts a two-stage approach: one stage converts the image into a "uniformly illuminated" appearance, and the other stage generates lighting effects based on user graffiti. This decomposition method simplifies the learning process and avoids external constraints that may need to be considered in a single stage, such as optical transmission consistency. LuminaBrush utilizes the "uniform illumination" appearance extracted from high-quality field images to construct paired data for training the final interactive illumination drawing model. In addition, the tool can also independently use the "uniform illumination stage" to "de illuminate" the image.
