Frigate+ new label: Umbrella?

[mdelecate]

In Frigate I currently also detect Umbrellas and treat those detections as equivalent to people in any automations.

In Frigate+, should I label people where most of their body is covered by an umbrella as "person"? Or would it be better to label them with a new label "umbrella"?

I think @blakeblackshear will have a better answer, but my intuition is that the the top image would be labeled as nothing and the bottom image could be a "person" with the difficult label checked.

Label persons that are partially visible. Don't label umbrellas as a person. I had never thought of this use case. I will consider adding umbrella in the next round of additions to Frigate+.

Ok, will do. When exactly should I tick "difficult"? What does it do in the backend?

Quoting #1043 (reply in thread) :

Difficult is a bit subjective, but I would say no on that one. It will be used when evaluating performance and possibly with training. I would consider a person barely visible through a tree or bush to be difficult. Basically anything you wouldn't expect a machine to be able to recognize.
