Can Haar cascade or LBP cascade classifier detect paper bill of different orientation, scale and lighting? or Do you have other suggestions regarding Paper bill Detection

I am currently working on a project which entails banknote detection before recognition. in order to assist the blind in taking photos of the banknote or paper bills.

Please put your questions in the actual body of the question and not in the title. As to if it is possible, yes it is. You will need to train a single orientation model, and then rotate the input image to detect on multiple orientations.

will it work if instead of rotating the input image i would like to train the cascade with several rotations or orientations?

Nope, because cascades are rigid models. Small rotations can be handled by a single orientation, but if you supply large rotational differences, the model gets so generic that it doesn't detect objects anymore.
