Title: Investigation of Segmentation Performances of Superpixel Algorithms for Noisy Images

Abstract: Superpixels, used espically in image and video segmentation applications, are the visiual structures composed of pixels having same color, intensity and texture behavior. In this work, segmentation performances of superpixel algorithms for noisy images are investigated. Moreoever, the effect of denoising to segmentation accuracy is also investigated. For this purpose, most common three superpixel algorithms are implemented to the images selected from image segmentation database. As a result of efforts made, noise sensitivity and segmentation performance of superpixel algorithms are investigated. Also, the effect of denoising process as a preprocessing step to the segmentation performance is also examined.

Keywords: Superpixel; image segmentation; noise

Başlık: Süperpiksel Algoritmalarının Gürültülü İmgeler İçin Bölütleme Performansının İncelenmesi

Özet: Süperpikseller, özellikle imge ve video bölütleme uygulamalarında kullanılan; bir imgeye veya videoya ait benzer renk, yoğunluk ve doku özellikleri benzerlik gösteren piksellerden oluşan görsel yapılardır. Bu çalışmada süperpiksel algoritmalarının gürültülü imgeler için bölütleme performansı incelenmiştir. Ayrıca, bölütleme uygulamalarında filtre kullanımının bölütleme performansına etkisi de incelenmiştir. Bu amaçla, en yaygın kullanılan üç süperpiksel algoritması imge bölütleme veri setinden seçilen imgelere uygulanmıştır. Gerçekleştirilen uygulamalar sonucunda, süperpiksel algoritmalarının gürültü bağışıklığı ve bölütleme performansları incelenmiştir. Ayrıca, ön işlem olarak filtre kullanımının bölütleme performansına olan etkisi incelenmiştir.
