i need a algorithm which detect all Indian currency in any way

can any one tell me howto work out with the opencv

i tried all examples provided in opencv but unable to get the exact accuracy

template matching only works in absence of rotation or perspective scaling.

also, if you have a multi class problem ("all indian currency"), this might be a poor tool.

you simply have to try more things, align your notes to principal axes, crop properly, maybe use machine-learning for the classification.

again, results will be proportional to your effort.
