Remove image background | Censhare Documentation

This is an Censhare Cloud feature.

You only see this feature if your Censhare Cloud instance has been set up for this.

This requires a valid license for the feature.

Introduction

The Remove background function keeps the main subject of your image and removes the rest. The result usually has a transparent background so that the subject can be placed on another color or layout.

Remove background

Open the function

Open an image and switch to the Editor tab.
Look in the toolbar.
Select the Remove background button:

If you do not see the button, the feature is not enabled at your Censhare Cloud instance.

Define the Background removal parameters

The Remove background dialog open:
Choose a Model which is used for removal. The selectoin box shows many different models which each of them is specific for special use-cases. For information on the models, see Appendix: Choose a model.

For more information, see Choose a model below.
Use for cleaner edges (optional):
1. Enable Alpha matting, for example if you have complex structures such as hair or a fleece.
2. Adjust the Foreground and Background thresholds.
Select Apply.
The removal process starts.

While the removal is running

While the background is being removed:

The editor may show a busy state.
Some tools may be temporarily disabled to avoid conflicting edits.
Saving may be blocked until the process finishes.

Messages you might see

When removal succeeds, you typically see a confirmation and an updated preview, for example:

Message	What it means	What you can do
Background removed	The new image is ready.	Continue editing or save.
Remove background failed	The process could not be completed.	Try again later. Contact your administrator if it keeps failing.
Failed to load … models. Using default model.	The model list could not be loaded	You can still continue. The default model is then used.

If you cancel removal process

If you cancel while the removal is still running, the editor may try to clean up the job status. The background removal can still finish in the background depending on how your system is configured.

Appendix: Choose a model

Depending on your system configuration, you can choose a model before applying background removal. If you’re not sure which one to pick, start with General. Then you can select to another based on what you see in the preview (hair edges, clothing details, etc.).

The model list in the dialog may look like this:
