[Note: The Inpainted Image display may take up to a minute depending on the Queue. The image and mask are resized to 512x512 before inpainting. The Run FcF-Inpainting button will automatically appear after you draw a mask.] To use FcF-Inpainting:
\
(1) Upload an Image or select a sample image on the left.
\
(2) Adjust the brush stroke width and draw the mask on the image. You may also change the drawing tool on the sidebar.
\
(3) After drawing a mask, click the Run FcF-Inpainting and witness the MAGIC! 🪄 ✨ ✨
\
(4) You may download/undo/redo/delete the changes on the image using the options below the image box.
