Instructions for the image cutout component-Platform For AI(PAI)-阿里云帮助中心

The image cutout component separates specific objects from an image. It is suitable for use in image semantic segmentation, image-to-text, and image and text explanation templates.

Function introduction

Area	Feature	Description	Keyboard shortcut
①	Move/Zoom in/Zoom out image	Move image: Click and drag to move. Zoom in: Click to zoom in. Zoom out: Click to zoom out.	alt+w/s/a/d: Move up, down, left, or right. alt+Up arrow/Down arrow: Zoom in or zoom out. alt+[]: Align the image left or right.
②	Interactive segmentation	Smart segmentation with a point-and-click operation. It uses the Segment Anything Model (SAM) by default. Left-click to add a positive point and right-click to add a negative point. For best results, use continuous operations. Add positive points to areas you want to keep and negative points to areas you want to remove. The points are cleared if you switch to another operation or undo the cutout.	None
③	Bounding box	Smart segmentation with a box selection operation. It uses SAM by default. After you draw a box, the tool automatically detects and segments the object inside it.	None
④	Rectangle selection	The Marquee Selection operation fills the area within the selection box, and you can Merge Or Subtract this area with other segmented areas of the same color.	None
⑤	Adjust edge	Draw a polygon for fine-grained matting and Close The Area to create a shape. You can then Merge Or Subtract this shape with other segmented areas of the current color.	Space bar: Quickly auto-close the shape. Backspace: Undo and return to the previous key point.
⑥	Magnetic lasso	Creates a precise cutout in Lasso Form by drawing a shape and Closing The Area. You can choose to Merge With Or Subtract From other segmented areas of the current color.	Space bar: Quickly auto-close the shape. Backspace: Undo and return to the previous key point.
⑦	Fill brush	Use a brush to fill the current operation mask with color. You can adjust the brush size.	None
⑧	Eraser	Erases only the colored area of the current operation mask. Other colors are not affected. You can adjust the brush size.	None
⑨	Undo/Redo cutout	Undo or redo a cutout operation.	None
⑩	Clear mask	Clears all masks and related data. Note When you clear the masks, data such as the masks and detail descriptions are cleared together.	None
⑪	Remove background area	Removes the background and displays all currently segmented objects. Click the icon to switch between a background color and a checkerboard pattern.	None
⑫	One-click hide (show original image)/Show all (show masks)	Hides or shows all current masks, letting you view the original image at any time.	None
