Bu çalışmada, Göktürk-2 keskinleştirme
yapılmış görüntüsünün kırsal ve kentsel bölgelerdeki başarısının
değerlendirilmesi amaçlanmıştır. Çalışma alanı olarak Trabzon ilinin Sürmene
ilçesi seçilmiştir.Görüntü keskinleştirmesi için 5m konumsal çözünürlüklü
dört adet Multispektral(MS) banda ve bir adet 2.5 m konumsal çözünürlüklü
Pankromatik (PAN) banda sahip Göktürk-2 uydu görüntüsü ve 0.5 m konumsal
çözünürlüklü Worldview-2 PAN bandı kullanılmıştır. İlk olarak, görüntülerin
ön işlemesi için Göktürk-2 MS ve PAN görüntüleri, Worldview-2 PAN görüntüsüne
göre piksel altı Root Mean Square (RMS) değeriyle geometrik olarak
düzeltilmiştir. Ardından Göktürk-2 MS ile Göktürk-2 PAN görüntüleri, ve
Göktürk-2 MS ile Worldview-2 PAN görüntülerinin sekiz farklı yöntem ile keskinleştirme
işlemi gerçekleştirilmiştir. Görüntü keskinleştirme işlemi için  Ehler's, Gram–Schimdt (GS), Hyperspherical
Colour Sphere (HCS), High-Pass Filter (HPF), Intensity Hue Saturation (IHS),
Principal Component (PC), Color Normalized (CN) ve Wavelet tabanlı yöntemleri
kullanılmıştır. Keskinleştirme yapılmış görüntülerin kalitesi yaygın olarak
kullanılan ve, spektral ve konumsal kaliteyi ölçen metrikler ile
değerlendirilmiştir. Ayrıca doku bilgisini çıkaran Gabor filtresi de bu
çalışmada metrik olarak kullanılmıştır. 
Bunun yanında keskinleştirme yapılmış görüntülerin değerlendirilmesi
için bitki ve su indisleri çıkarılmıştır. Orijinal ve keskinleştirme yapılmış
görüntülerin indisleri arasındaki korelâsyon katsayıları hesaplatılmıştır.
Değerlendirme sonucuna göre, kentsel alan için CN , kırsal alanda ise HPF ve
HCS görüntü keskinleştirme yöntemleri ile elde edilen sonuçların  spektral ve konumsal anlamda daha az
bozulmaya sahip olduğu görülmüştür. 
Genel olarak kentsel ve kırsal alan için  CN yönteminin doku bilgisini daha iyi
yansıttığı ve indisler yönünden de daha yüksek korelâsyona sahip olduğu
gözlenmiştir.

In this study, 
it is aimed assessment of success of Göktürk-2 fused image for urban
and rural regions. Sürmene distict of Trabzon were selected as study area.
For image fusion, Göktürk-2 space borne sensor, which captures data in four
Multispectral MS (5 m spatial resolution) bands and one Panchromatic
(PAN) (2.5 m spatial resolution) band,and Worldview-2 PAN (0.5 m spatial
resolution) band were used. Firstly, for the images pre-processing Göktürk-2
MS and PAN images were registered by using Worldview-2 PAN images as  sub-pixel RMS value. And then Göktürk-2 MS
and Göktürk-2 PAN images, and Göktürk-2 MS and Worldview-2 PAN images were
fused with the eight different methods. It was used Ehler's, Gram–Schimdt
(GS), Hyperspherical Colour Sphere (HCS), High-Pass Filter (HPF), Intensity
Hue Saturation (IHS), Principal Component (PC), Color Normalized (CN) and
Wavelet based methods for image fusion. Quality of fused images were assessed
commonly used metrics that measures the spectral and spatial quality. Also
Gabor filter that extracts  texture
information was used as metric. Furhermore, Vegetation and water indices were
exploited to assess the fused images. The correlation coefficient between the
indices of the original and the fused images was calculated. As a result of
evaluation, it was seen that for urban CN, 
for rural  HPF and HCS  fusion methods had less deterioration in
spectral and spatial terms. Generally, it has been observed that CN methods
better reflect texture information in and 
has a higher correlation in terms of indices urban and rural areas.
