# Input Masks and ROI

Use inclusion, exclusion, and ROI masks to limit what the AI Manager sees.

Inclusion and exclusion areas add a mask over the image sent to the AI Manager. The Region of Interest (ROI) removes all information outside the designated region and sends only the information inside the rectangle to the AI Manager.

{% hint style="warning" %}
Using an input mask and a region of interest at the same time is not supported.
{% endhint %}

## Custom External Processing

To customize this behavior, create a preprocessor to build a mask, or a postprocessor to exclude results from a designated area.

For examples of custom preprocessors and postprocessors, see the sclbl-integration-sdk repository:
