Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Please explain more about your question. I may or may not be able to help with your question, but will pass it to whomever is best suited, after hearing more about it.
(Points that really need clarification in your initial posting to this case:
- how "food image recognition" relates to C++ coding
- what a "bad of SURF features" is, in that context
- and anything else you care to mention, and lastly, how soon you need this completed.)
