Indian currency detection using opencv with C++

Question

I am new to opencv. I have a problem statement which says:
Detecting Indian currency and identifying it's genuinity.

The program needs to be written in c++. I am not aware of algorithms/apis available which can be used for this purpose. The expectation is to print the value of note (10/100/500 etc) considering both old and new currency note images. Also the genuinity of note needs to be printed. UV and florocence detections cannot be used in this case. Could any one suggest how to start about with this.

Thanks.

What I have tried:

Since I am very new to opencv, I am not aware of anything here. But I went through few examples and some content available in tutorials.

First, you're going to have to learn how to use OpenCV. We can't tell you everything you're going to need to know in a few forum posts. You can start here[^].

Next, you're going to have to dig into object recognition. Be warned, this is far from a trivial tasks.

DO NOT EXPECT TO DETECT COUNTERFEIT CURRENCY! Sure, you're going to be able to detect the obvious fakes, like someone hand drawing a note, but the stuff that counterfeiters put their pride into is going to look exactly like the real thing to your code.
