One person in an image - "Select Subject" and "Select People" return very different results (26.8.0)

...specifically the result of "Select Subject" is phenomenal and the result of "Select People" is as it was, or maybe even worse?

Is this intnetional behaivior? Is the engine for "select subject" entreily different than "select people" (or object finder for that matter)?

"Results from cloud" is selected wherever possible so this is not (I hope) a difference of local processing vs. cloud precessing.

Yeah, you're not imagining it—"Select Subject" and "Select People" can produce different results, even when there's only one person in the image. From what I understand, they do use different models under the hood.

"Select Subject" has gotten significant improvements lately and is more generalized—it looks at the entire composition and picks out the most prominent subject, which often results in a cleaner edge and better detail. "Select People," on the other hand, is more specific to facial/body region detection and sometimes struggles with things like hair or subtle edge transitions, especially in complex backgrounds.

Select Subject has been around for longer than Object Selection: People. 

 

Perhaps the AI isn't trained on the same depth of data, I don't know.

 

Work with what produces the best results, definitely cloud processing for Select Subject (local processing on the left, cloud on the right).

Your instincts may be correct, robert.

Hover hints for each tool --

Select people: "Select people and attributes related to people with simple clicks."

Select Subject: "Create a selection from the most prominent objects in the image."

Subject, Object and People are not synonyms, and seem to be handled differently.

 

Extensive help makes a good read. Help>, search for "select subject or object in your images" (the first entry in the Help section).

I think the section 'Get precise selections of people and their details with Select people' is helpful.

 

Batter up, experts!
