Abstract
Tanda tangan adalah salah satu keunikan yang dimiliki oleh setiap orang
sehingga seringkali dipakai dalam menentukan keabsahan dari suatu dokumen
atau transaksi. Sistem yang dibuat bertujuan untuk melakukan pengenalan tanda
tangan secara efisien serta mengetahui manfaat pengolahan citra digital dan
jaringan saraf tiruan Radial Basis Function dalam dunia nyata.
Sistem ini dibuat dengan menerapkan pengolahan citra digital dan
pemanfaatan jaringan saraf tiruan Radial Basis Function. Citra tanda tangan yang
akan dilatih atau diuji harus melalui beberapa proses pengolahan citra digital yaitu
proses pengubahan citra menjadi citra keabuan (grayscale), pengambangan
(thresholding), segmentasi citra (segmentation), normalisasi ukuran citra (size
normalization), thinning, dan pembagian citra ke dalam wilayah-wilayah (region)
yang akan menghasilkan nilai-nilai untuk selanjutnya diproses dengan jaringan
saraf tiruan Radial Basis Function. Pemanfaatan jaringan saraf tiruan Radial Basis
Function dimulai dengan pelatihan terhadap sampel tanda tangan dari setiap
responden yang telah diolah. Setelah proses pelatihan selesai maka sebuah citra
tanda tangan milik salah satu responden yang telah dilatih dapat dikenali oleh
sistem.
Pengolahan citra tanda tangan dan jaringan saraf tiruan Radial Basis
Function yang diterapkan dalam sistem berhasil melakukan pengenalan terhadap
beberapa citra tanda tangan. Penelitian ini menguji 100 citra tanda tangan yang
berasal dari 10 responden yang telah masing-masing telah memberikan lima citra
tanda tangan untuk pelatihan sistem. Tingkat akurasi dari hasil pengujian tersebut
sebesar 88% dimana terdapat 88 tanda tangan yang dapat dikenali dengan benar
dan 12 tanda tangan yang gagal dikenali. / Signature is one of the each individual’s uniqueness; therefore this is often
used to determine the authenticity of a document or transaction. The system is
being created to efficiently recognize a signature, this also determine the function
of digital image processing and Radial Basis Function neural network as
implemented in the actual basis.
This system is made by implementing digital image processing and the
usage of Radial Basis Function neural network. Signature image that will be
exercised or tested has to follow few digital image processes namely grayscale,
threshold, segmentation, size normalization, thinning, and region to produce
values which subsequently will be processed using Radial Basis Function neural
network. The usage of Radial Basis Function neural network is started by
conducting exercise toward processed signature sample from each respondent.
After exercise process is finished, then a signature image owned by a respondent
who has been exercised can be recognized by the system.
The signature image process and Radial Basis Function neural network
which has been implemented in the system successfully recognizes few signature
image. This research tests 100 signature images which comes from 10 respondents
which individually has provided five signatures to system exercise. The accuracy
degree from testing result is 88% where there are 88 signatures that can be
correctly recognized while the 12 signatures are failed to be identified.
