Unique Image Recognition

Hi,

   I tried the image scanning with cloud set up. Am good with the flow and the steps which has provided in your sample app. But the challenge here is to recognize the image uniquely. 

My use case is like, user has to scan a product logo on any object or poster on a wall in a store. It may be in any color. For example, when i scan a (NIKE) logo on my shoes with text or without text.Then the  app should recognize this image has NIKE. How could I achieve this implementation by using vuforia SDK. Kindly help me get the same with sample demo app or guide me the steps to implement the same.

Thanks ,
