Studies to classify bird species on the basis of images are very difficult due to both the abundance of colors and patterns in the image, and their very close visual characteristics. In this study, six different deep learning models have been applied for the classification of bird species and the experimental results have been compared comprehensively. A dataset named 250 Bird Species, which includes a total of 31316 bird images with 225 bird species, was used as dataset. In the study, 1125 images have been used for the test and 1125 images for the validation. The comparison of VGG16, ResNet50, ResNet152V2, InceptionV3, MobileNet and DenseNet121 deep learning models have been made on the dataset respectively, according to the accuracy, precision, recall and F1-score values. In experimental studies, 94.6% accuracy value has been obtained with VGG16, 47.2% with ResNet50, 96.2% with ResNet152V2, 97.5% with InceptionV3, 96.9% with MobileNet and 98.2% with DenseNet121. DenseNet121 obtained the highest precision value as 0.99, sensitivity value as 0.99 and F1-score value as 0.99.

Derin Öğrenme ile Kuş Türü Sınıflandırma: Karşılaştırmalı Bir Çalışma

Öz

Kuş türlerini görüntü üzerinden sınıflandırmaya yönelik çalışmalar hem görüntü içerisindeki renk ve desen çokluğu hem de birbirine çok yakın görsel özelliklere sahip olmalarından dolayı oldukça zordur. Bu çalışmada kuş türlerinin sınıflandırması için altı farklı derin öğrenme modeli uygulanmış ve deneysel sonuçlar kapsamlı bir şekilde karşılaştırılmıştır. Veri kümesi olarak 225 kuş türüne sahip toplam 31316 kuş görüntüsü olan 250 Bird Species isimli veri kümesi kullanılmıştır. Çalışmada 1125 tane görüntü test ve 1125 tane görüntü ise doğrulama için kullanılmı ştır. Veri kümesi üzerinde sırasıyla VGG16, ResNet50, ResNet152V2, InceptionV3, MobileNet ve DenseNet121 derin öğrenme modellerinin doğruluk, kesinlik, hassasiyet ve F1-skoru değerlerine göre karşılaştırması yapılmıştır. Yapılan deneysel çalışmalarda, VGG16 ile %94,6, ResNet50 ile %47,2, ResNet152V2 ile %96,2, InceptionV3 ile %97,5, MobileNet ile %96,9 ve DenseNet121 ile %98,2 doğruluk değerleri elde edilmiştir. En yüksek kesinlik değeri 0,99, hassasiyet değeri 0,99 ve F1-skor değeri 0,99 olarak DenseNet121 ile elde edilmiştir.
