Image Recognition for Apps

by choc
1 replies
Was wondering if any programmers were familiar with image recognition platforms/APIs such as Google Goggles, Kooaba, Snaptell, etc.

Question: are there any free APIs that have reliable image recognition functionalities? Also, how does the AI function? Does the AI match the image against an online database? If not, how?

Google Goggles has yet to have an API release, but Kooaba has a p2p platform... Any free or cheaper alternatives to Kooaba?

Thanks all!

    There are only a few ways to do image recognition. Most at least START with defining some metric, and recording that on all pictures. When an apparent match is made, it has to do some sort of vector analysis OR, if they are VERY lucky, bitmap compare. That is also how afis works. Of course, matches won't be 100%, so they have to do some sort of filtering ALSO. THAT is why they use a green screen when copying an image to replace another. They know that the image they want is all that is NOT that shade of green.
