Nowadays, with the development of technology, there is a possibility of corruption of the image due to some
disturbing effects during the image retrieval from the external world. One of these disruptive effects is salt and
pepper noise. In this paper, a new filter which called Euclidean Distance Based Adaptive Filter (EDBAF) is
proposed to remove salt and pepper noise. In this approach, it is calculated how much the noiseless pixels in the
process pixel will affect the center pixel than the center pixel distances. In this way, it has been performed to
image enhancement. This approach has been tested on different test images with different image quality
parameters. It has been verified that it is better at low and high noise density than other existing filters.

Öklid Mesafe Tabanlı Uyarlamalı Filtre Kullanılarak Tuz Biber Gürültüsü Giderimi

Günümüzde teknolojinin gelişmesiyle dış dünyadan görüntülerin alınması aşamasında bazı bozucu etkilerden
dolayı görüntülerin bozulması söz konusudur. Bu bozucu etkilerden biri de tuz ve biber gürültüsüdür. Bu yazıda,
tuz ve biber gürültülerinin giderilmesi için Öklid Mesafesi Tabanlı Uyarlamalı Filtre (Euclidean Distance Based
Adaptive Filter-EDBAF) isimli yeni bir filtre önerilmektedir. Bu yaklaşımda işlem pencerelerindeki gürültüsüz
piksellerin merkez piksele olan mesafelerine göre merkez piksele ne kadar etki edeceği hesaplanmaktadır. Bu
sayede imgenin iyileştirilmesi gerçekleştirilmektedir. Bu yaklaşım farklı test imgeleri üzerinde farklı görüntü
kalitesi parametreleri üzerinden test edilmiştir. Diğer mevcut filtrelere oranla düşük ve yüksek gürültü
yoğunluğunda daha iyi sonuç verdiği doğrulanmıştır.
