Nearby items lacking a "good" picture

Question: What will I do after all WIkidata items in my area have a picture?
Answer: Show me items that need a "better" picture!

"Better" ca be hard to define, but an algorithm will be able to take a good guess using the picture's:
Photographic quality:

• Size
• Contrast
• Fourier high frequencies
• Implementations welcome at https://softwarerecs.stackexchange.com/questions/30832/assessing-the-quality-of-an-image
  Quality in context:
• Date at which the picture was taken (a 1985 picture is not as good as a picture taken this year, even if it has the same photographic qualities)
• Does it really represent the subject well? This could be a system of "stars" given by humans.

A database of items pictures quality would be hosted on a WMF server, and be queryable by geographical proximity.
That's a long-term endeavor, which is not a problem since it is low-urgency.

Example of an item with a "bad" picture: https://www.wikidata.org/wiki/Q17229541 https://commons.wikimedia.org/wiki/File:Root_stilted_black_pine_at_Naruto.png

Or lacking "an adequate number of pics". Not sure if we would read such information from Wikidata, or rather from associated Commons categories?

In Wikidata, the appropriate number of pictures is always 1. (at least for geographical things)

I often check how many low resolution images an item has in the corresponding Wikidata category to decide whether I need to take new ones, so I agree that automatic criteria can help.

However, for manual requests of images there's also https://tools.wmflabs.org/wiki-needs-pictures/

I suspect the validity of that. I just now added a second image to a geographical place.

@sivaraam While adding several images for an item is technically doable due to historical reasons, it is not desirable.
This is discussed at https://www.wikidata.org/wiki/Property_talk:P18#How_many_images.3F
Geographical items that have more than 1 image have the extra ones removed regularly.
Cheers!

Structured Commons will introduce a "quality assessment" property for media.
I suggest using that value, it will be queryable.
Hopefully other Commons communities will find smart ways to quickly assess the quality of all media.
