Feature request: Automatic highlight reels via OpenCV?

[bryan at gillson.net]

Has the team considered using OpenCV for more than facial/object recognition given the recent improvements to the AI pipelines in 8.5/8.6 (thank you Mike!)?

I'm hoping for something similar to iPhoto's auto-generated highlight reels where DigiKam would identify a quick-and-dirty "good enough" sampling and representation of the contents of a folder. This would save hours of manual labor: Just selecting vacation highlights can be incredibly time consuming and intimidating when the folder contains well over 1,000 photos from my wife, children, and I with many overlapping subjects, duplicates, errant or "failed experiment" photos, etc.

These Highlights don't need to be some Platonic ideal "best" photos (whatever that means), and certainly wouldn't replace human-centric selection of the perfect pose and expression. However, qualitatively decent pictures could be selected using AI-based criteria such as focus/sharpness, visual clutter, uniqueness, and rule of thirds composition. I don't need 100 elephant pictures from the zoo; just pick a few good ones. Just pick one of the 6 group pictures (even if someone's eyes are closed, I can always refine it later). Skip the 15 pictures taken of the inside of my pocket. Et cetera.

Ideally, Highlight photos could be selected to be further manually tagged, starred, labelled, or otherwise entered into existing workflows. Or, they could just be copied directly to a slideshow, photo frame, or email, knowing they capture the gist of a folder.

Would others find such a feature useful? Or is DigiKam already capable of something like this and I'm just not aware of it?

Thanks!
