Replace the background for an image - Amazon SageMaker Unified Studio

Amazon SageMaker Unified Studio is in preview release and is subject to change.

Replace the background for an image

The following procedure shows you how to use a model to replace the background for an image. For example, you could change the background for an image from a view of a forest to a view of city buildings. You can set various configurations such as the number of images to generate and how strongly the prompt affects the generation of the image. For more information, see Configuration options.

Note

The background replacement action is only available with Titan Image Generator G1 V1 and Titan Image Generator G1 V2 models.

To replace the background for an image

  1. Navigate to the Amazon SageMaker Unified Studio landing page by using the URL from your admininstrator.

  2. Access Amazon SageMaker Unified Studio using your IAM or single sign-on (SSO) credentials. For more information, see Access Amazon SageMaker Unified Studio.

  3. At the top of the page, choose the Discover.

  4. In the GENERATIVE AI section, choose Image and video playground.

  5. If the Configurations pane isn't open, choose the configuration button.

  6. For Model select a model to use.

  7. For Action choose Replace background.

  8. (Optional) For Negative prompt enter text that describes content or concepts that you don't want the model to include in the image.

  9. In Reference image choose Upload image and upload the image that you want the model to use with the action.

  10. (Optional) For Negative prompt enter text that describes content or concepts that you do not want the model to include in the image.

  11. (Optional) In Advanced configurations, change how the model generates images by making advanced configuration changes. For more information, see Advanced configuration options.

  12. In the center pane, use the masking tool to draw a bounding box around the area of the image that you want the action to preserve. The model updates the area outside of the bounding box. You can do the following:

    1. Resize the bounding box by selecting a corner of the bounding box with your mouse button. Then, drag the mouse to resize the bounding box. Release the mouse button to complete resizing the bounding box.

    2. Move the bounding box by selecting the interior of the bounding box with your mouse button. Move the bounding box to the new location and release the mouse button.

  13. In the Enter prompt text box, enter a prompt that describes the background that you want the image to have.

  14. Press Enter on your keyboard to start the action. Amazon Bedrock IDE shows the image that the model generates in the playground.
