There are many excellent posts and answers referencing data sources. However I can't seem to find many for food image/photograph recognition. I would have thought, with so many people taking and uploading pictures of their food, that this should be readily available. Can anyone help? Food101 and UEC are good but limited. Thank you.
I would suggest Pittsburgh Fast Food Dataset http://pfid.rit.albany.edu/ You might find it limited, but you can join it with the other available datasets.
