Android Image recognition

Question

I have a particular problem about image recognition on Android. I am looking for some library able to recognize several objects from a photo. For instance, given a photo snapped by the user how can I count how many red circles and yellow triangles there are? Those shapes are just an example, since I want to recognize images which are pretty simple. I have seen that there exists a good framework called Vuforia, which is designed for augmented reality. Do you think it is right for me? I am not an expert, so I ask you to help me.

Solution

check OpenCV for that, open source and works great on android

or

OpenCv
