Avuç içi doğrulama, biyometrik doğrulama içinde en yaygın kullanıma sahip yöntemlerden birisidir. 2019 yılının son aylarında ortaya çıkan COVID-19 (Coronavirus Disease 2019) pandemisi insanların ortak kullanıma sahip nesnelere temas konusundaki duyarlılığını artırmıştır. Bu sebeple, temassız şekilde elde edilen görüntülerin kullanıldığı avuç içi doğrulama çalışmalarının yapılması önem kazanmaktadır. Çalışmada, Hong Kong Politeknik Üniversitesi Temassız 3B/2B Veri Seti (Sürüm 1.0) (PolyU Contactless Database 1.0) kullanılmış olup doğrulama için Siyam Sinir Ağlarından (SSA) yararlanılmıştır. SSA eğitimleri 3.540 adet “benzer” ve 31.152 adet “benzemeyen” olmak üzere toplam 34.692 adet görüntü çifti kullanılarak gerçekleştirilmiştir. Çalışmanın test işlemleri ise 885 adet “gerçek” ve 31.152 adet “sahte” olmak üzere toplam 32.037 adet giriş örneği kullanılarak yapılmıştır. Çalışmada, avuç içi görüntüleri doğrudan kullanılarak elde edilen doğrulama sonuçları ile ön işlem olarak Yerel İkili Örüntü (YİÖ) kullanılarak elde edilen doğrulama sonuçları birbirleriyle karşılaştırılmıştır. Çalışma sonuçları ön işlem olarak YİÖ kullanılmasının doğrulama başarısını önemli ölçüde iyileştirdiğini göstermektedir. Çalışmada, avuç içi görüntüleri doğrudan kullanılarak elde edilen Eşit Hata Oranı (EHO) 0,1277 iken ön işlem olarak YİÖ kullanılarak elde edilen EHO 0,0938 olarak gerçekleşmiştir.</p></abstract>

                            <p>Biometric authentication is the confirmation of whether people are really the person they claim by using their physiological or behavioral characteristics. Palm verification is one of the most widely used methods in biometric verification. The COVID-19 (Coronavirus Disease 2019) pandemic emerging in the last months of 2019 has increased people&#039;s sensitivity to contact with objects of common use. In the study, Hong Kong Polytechnic University Contactless 3D/2D Dataset (Version 1.0) (PolyU Contactless Database 1.0) and Siamese Neural Networks (SNN) were used for validation. SNN trainings were carried out using a total of 34,692 pairs of images, of which 3,540 were &quot;similar&quot; and 31,152 were &quot;dissimilar&quot;. Testing of the study was carried out using a total of 32,037 input samples, 885 of which were &quot;real&quot; and 31,152 were &quot;fake&quot;. In the present study, the validation results were obtained using the palm images directly and the validation results were obtained by using Local Binary Pattern (LBP) as a pre-process. Then, these results were compared with each other. The results of the study show that the use of LBP as a pre-process significantly improves the validation success. In the study, while the Equal Error Rate (EER) obtained by using the palm images directly was 0.1277, the EER obtained by using the LBP as a pre-process was 0.0938.</p></trans-abstract>
