Hello Gurus,
I am hoping that the wise would guide the misguided here :).
I am trying to detect a curve of a certain shape and its position from a signal as shown below: 
. Due to noise and other variations, the curve may not be exact so I can not use simple number matching. I was wondering if there is something in OpenCV which I can use for this.
Note that I will need to detect curves of different shapes and their position in the signal but if I know to detect one type, I can use the same method to detect other types.
Your help is appreciated. Thanks, Peter
