Workflow name: Christmas product photography OminiControl
[Workflow introduction]
First open the workflow, upload a white background image of the product, reverse the image through Runninghub Captioner, use 🔥BiRefNet to cut out the image and fill the background, and generate the image through OminiControl Subject. Then use the Plux-fill-dev model to expand the generated image. Now the built-in parameters have been set. Come and experience it!

[Use scenario]
This workflow can quickly change the background of your product. By using the external drawing board to change the size of the main image, the product can be better integrated into the scene, which greatly improves the work efficiency of e-commerce.
