Use this tool to create masks from your images. Masks are very useful when combined with ControlNet, and specially the CN InPaint model.
A mask is an image with clear areas, when used with the InPaint ControlNet model, the generation process will focus on filling the clear areas of the image. This is a really powerful solution when you wish to remove objects from an image, change background, subjects, faces, etc.
The tool works as a "lasso" tool. Simply outline the area you wish to mask.
Reset: Removes all drawn areas and restores the original image state. Invert: Inverts the selected areas. For example: if you cleared the subject of the image, you can use the Invert button to clear the background instead. Apply: Applies the new mask to the original image, making it ready to use with the ControlNet module, Gallery, etc. and exits the Tool. InPaint: Sets the masked image as the ControlNet image, and loads the CN InPaint model. This is a quick way to configure ControlNet to fill the empty areas in the image, just click Dream to generate the image when the setup is complete.
Step One
Open the image you'd like to create a mask within and select the Mask Tool from the top Toolbar.
Step Two
Highlight the area you would like to use as a mask, then select InPaint to open up your image with your Mask in ControlNet with the InPaint CN Model applied.
Step Three
Enter your prompt within the prompt field to regenerate your image with your Mask ✨
The Segmentation preprocessor in ControlNet can help you to automatically mask the subject/background of your image. Here is how to use it:
1. Drag the image you wish to mask to the controlNet module.
2. Select the Segmentation preprocessor (second one from the bottom on the left side of the CN image)
3. Enable the subject or background mask button and make sure you have transparent background selected. These should create the mask you need with only the subject or background.
4. If you need to remove more areas from the mask, click the “Send to Main Window” button to the right of the CN image, then activate the "Lasso Eraser / Mask Tool".
