How to use surf as an object detection for multiple objects?
I am woking on a money identifier for the blind and i want a feature which can detect if a money presented infront of the camera
You need to learn the difference between object detection and object recognition. Detection is to define if some class, in this case bills, is present or not in the image. Classification is to define if a specific item or subclass is available once the localisation is done. The second part can be done with SURF or any other feature detector, the first one can't if you want to cope with natural variance in objects.
