For the demo I saw, you select an example image from a visual list or keyword search and the software then returns images based on similar visual properties. So keywords (often poorly assigned) don't preclude good hits, and the hits don't include irrelevant images.
It seems like one effective solution for searching stock photography quickly.
Has anybody seen anything other then evisionglobal's software?
For an example try an image search for horse. The results are quite impressive
(now if I can just find a shameless plug forum I can get my money from AltaVista)
The tutorial says that the results list will have a "similar" option which "generates a results page containing images that are visually similar to the selected image as well as pages with content that matches your search. Similarity is based on visual characteristics such as dominant colors, shapes and textures."
But I couldn't get that option, so I'm guessing that this visual search is either still in the works, or I'm doing something wrong...
Having family filter on prevents the "similar" option.
It's interesting, but I think they're only matching similar color histograms - kind of crude. I did a "similar" search on an eagle, and got results with similar color distribution, but that's about it. It's a visual search, but doesn't seem to use shape or texture, only relative color proportion.
The evisionglobal demo I saw ranks so far.
There's a new article about visual search at [webreference.com...] which talks about this process in-depth. I liked the idea of searching by object regions, which seems to cut through some of the limitations at Altavista.
I thought the visual search technology overview at [evisionglobal.com...] was pretty comprehensive. At least I could see object-based visual searching used in databases for things like medical imaging and other fields where there are lots of very similar but still different graph and chart images.
I wonder if something like this could be used as a porn filter too? Sort of the same function, but backwards...
