Matching of Feature Points for Moneynote Fragment Assembly

Banknotes, known as a bill, paper money, or simply a note, may be shredded by a scrap machine, ripped up by hand, or damaged in accidents. To assemble broken money note pieces is one of the time-consuming tasks encountered by forensic institutes. This paper proposes an effective scheme to match feature points and rotate the orientation of each fragment for banknote assembly. The experimental results show that the proposed scheme achieves the least errors in the estimated rotation angle.
