Abstract
Derin
öğrenme metotları bilgisayarlı görme ve görüntü işlemede özellikle de görüntü
sınıflandırma probleminde önemli bir teknoloji haline gelmiştir. Bunun en
önemli nedenlerinden biri farklı problemler üzerinde derin öğrenmenin göstermiş
olduğu üstün başarıdır. İnternetin gelişimi ile çok büyük veri kümeleri
toplanmakta ve yüksek güçlü grafik işlemci kartlar ile bu veriler gerçek
zamanlı olarak işlenebilmektedir. Fakat her problemler için bu şekilde büyük
ölçekli veri toplamak oldukça maliyetli bir işlemdir. Bu amaçla ön eğitilmiş
derin öğrenme modelleri transfer öğrenme yöntemi ile daha düşük boyuttaki
verileri sınıflandırmak için kullanılabilir. Bu çalışmada X-ray cihazlarından
alınan görüntülerde tehdit unsuru içeren nesneleri sınıflandırmak için transfer
öğrenme yöntemi ile gömülü ve gerçek zamanlı çalışabilen bir sistem
geliştirilmiştir. Bu sistem Nvidia Jetson TX2 geliştirme kartı üzerinde bir
evrişimsel sinir ağı olan Alexnet derin öğrenme modeli kullanmaktadır. Bu model
ile X-ray bagaj güvenlik görüntüleri içerisindeki bıçak, silah, jilet ve Ninja
yıldızı gibi tehdit unsuru içeren nesneler sınıflandırılmıştır. Oluşturulan deney ortamında Alexnet 12.000
görüntü ile eğitilmiş ve gerçek ortamda test edilmiştir. Önerilen yöntemin
performansı aynı veri kümesi üzerinde daha önce yapılan farklı bilgisayarlı
görme teknikleri ile karşılaştırılmış ve daha başarılı sonuçlar elde edilmiştir.
