Iraqi Currency Recognition and Identification Using SIFT

Many currencies belong to different countries worldwide, currency recognition via visible and invisible watermarks in paper currency is a new technology used for good currency classification, Currency recognition can be used to help human for easily detection the currency and if able convert it to another currencies without any supervision. Iraqi currency is used in this paper for recognition and identification. All the Iraqi paper currencies are tested and recognized. The sampled used (different view sides and blurry images tested), complex designs used for currency security, thus the recognition is difficult, Scale Invariant Feature Transform (SIFT) for feature extraction and detection is used for this purpose which provide efficiency, high speed, min complexity and can be used with different currencies.
