I am trying define zones that the sensor shouldn't care about, that can be excluded. Is there a simple way to do this?
The Region of Interest, will select a rectangular region of interest. If you are interested in more detailed masking of areas, then the suggestion would be to create a binary mask (0 and 255, 0 for areas to be masked and 255 for areas not to be masked). The input can be ANDed to this mask in the source codes.
You can using the Region Of Interest setting to do detection only in the regions that have been selected. Please refer the GUI User guide section called Selecting Region of Interest which explains how to do this.
