Auto Exposure on ROI
====================

This example shows how to dynamically set the Auto Exposure (AE) of the RGB camera dynamically, during application runtime,
based on bounding box position.

By default, AutoExposure region is adjusted based on neural network output. If desired, the region can be set manually.
You can do so by pressing one of the following buttons:

- `w` - move AE region up
- `s` - move AE region down
- `a` - move AE region left
- `d` - move AE region right
- `n` - deactivate manual region (switch back to nn-based roi)
