Real-Time Recognition of Series Seven New Zealand Banknotes

Yan, Wei Qi; Ren, Yueqiu; Nguyen, Minh - In: International Journal of Digital Crime and Forensics (IJDCF) 10 (2018) 3, pp. 50-65

This article proposes an effective method for real-time banknote recognition, using digital image processing. The new Series 7 New Zealand banknotes are considered, as a case study, for intelligent real-time recognition. The composite feature of a banknote containing the elements of color and...
