Let's limit within object recognition only, for the sake of simplicity. A few examples are coffee beans, plant diseases, knitting styles.
I believe with the advent of the digital picture age and $15 128GB SDCards. People have so many pictures they can't manage, they will rely on anything that gives them a bit of control with minimal effort: FB w/ facial recognition.
I believe the singular aspect of what a camera should be able id faces. Then embed that info in the metadata to be pulled later.
The caveat to that is it must be kept private, never be uploaded onto a cloud and metadata encrypted.
Although like others, I have GBytes of pictures but the only ones precious enough to keep track of are the ones with faces on them. Object recognition, yeah kool but if I could query: find all pics of my son. BAM! be very happy.
So to give up my idea I'll never implement: 1. ID faces but only locally. 2. Embed face info as metadata of the picture file. 3. Crawler that walks regularly through all your pictures AND videos and ID's faces. 4. A natural query language to find all pics by relationship, name, age, sex, time and date
Re-reading your question, failed to initially understand. sorry.
Your question has already been answered: Google Lens. Matter of fact, i just used it on a tree I couldn't ID so I took a pic of it using Googl Lens and voila with their long reach search arm, BAM! I found it. I've done this many time befores with the Lens app. So not sure what more you can add to what seem to already work as your looking for?
Also distances could be computed from camera + gps or accelerometer?
Actors in TV and Internet advertisements
Animal scat or Animal footprints
What the stains on someones clothes were made from (yuck)
How many jelly beans or whatever are in a jar
The freshness of produce (especially those pre-made salads that can wilt before you get them home)
Poisonous plants and mushrooms
2. Who is this person? (With regards to event attendees, not a random girl on the train)
3. Is this chicken supposed to be this color? Is this avocado ripe?
4. Is this the russet potato my wife wanted me to buy?
