Advice on Object Recognition I am working on a project where I want to recognize the symbols of electronics components. In the image, I extracted resistor symbol, capacitor symbol, etc and now I want to recognize the symbol. Symbol could be oriented in any angle and there are many symbols to show a resistor. Resistor symbol might be long or short. I am using perfectly shaped and aligned circuits made in some drawing software.

I was thinking of using Bag of Words classifier but I think BoW is too complicated for such object recognition and even getting images for classifier is bit difficult.

I want some advice about what type of object recognition techniques can be used to recognize these kinds of circuit symbols.
