Hide portion of saved video frame

[frank]

I am using AI to identify vehicles that enter my driveway. When motion is detected on the driveway, a single frame is saved and then AI is called to identify the vehicle. AI will grab the most recent frame taken and identify the vehicle. A table is referred to which ties the vehicle to a person's name and that name is announced on Alexas and home intercom.

Problem is sometimes a car is parked on the street or on the neighbor's driveway or happens to be driving by. AI is confused by this. Or sometimes an event is triggered by false motion detection and AI will look at the frame and identify a vehicle not parked on my driveway.

I'd like to block areas outside of my property from showing up in the saved picture files.

The "blocked" areas could be rectangular or triangular in shape.

Is such a setting available in Blue Iris?

Thank you!

Could this be it? This is in the trigger section which seems misplaced if it is a record setting.

thanks !!

I did try that, but it seemed to be related to triggering. I got the idea, which could be wrong, that the setting reverses what is being watched.

So far, I'm using a little script to block out the "triangles of the frame that I don't want AI Bot to see. I'll attempt to attach the resulting graphic...

The smaller triangle has three sides. The larger polygon / triangle has 6 sides. I had to "curve" the hypotenuse to match up with the street.

This works well because the video you see is complete. Only AI bot sees the blocked image.

thank you for your interest!
