Abstract

In this study, homogeneous rays were
determined by using image processing methods in hardwood and softwood (Abies
alba Mill, Tilia platyphyllos Scop., Tilia cordata Mill, Betula alba, Juglans
regia L. Walnut, Ulmus scabra Mill). The rays that parenchyma
cells are come together, have a porous structure in tangential section. Since
the rays are composed of small parenchyma cells, large regions were removed
from the image after thresholding. The regions that high/width ratio was high
were deleted from the image. One of the morphological processes, the close
process was combined with the parenchyma cells after rays were determined.
Non-combining and non-rays regions were deleted. The expansion and filling
process determined the final shape of the rays. The results were given
statistically and visually. As a result of the analysis; maximum and minimum
rays were determined Ulmus scabra Mill. and Abies alba Mill. respectively.
Systems that find the rays automatically by utilizing image-processing techniques
appropriate to the structure to be determined ensure that the study of wood
anatomy is done in a short time and more easily.

YAPRAKLI VE İĞNE YAPRAKLI AĞAÇLARDA HOMOJEN ÖZ IŞINLARIN MORFOLOJİK İŞLEMLERLE BELİRLENMESİ

Abstract

Bu çalışmada, yapraklı ve iğne
yapraklı ağaçlarda (Abies alba Mill, Tilia platyphyllos Scop., Tilia cordata Mill,
Betula alba, Juglans regia L. Walnut, Ulmus scabra
Mill) bulunan homojen öz ışınları görüntü işleme metotları kullanılarak
belirlenmiştir. Öz ışınları paranşim hücrelerin bir araya gelmesiyle oluşur ve
teğet kesitte gözenekli bir yapıya sahiptir. Küçük paranşim hücrelerinden
oluştuğu için eşikleme işleminden sonra büyük bölgeler görüntüden
çıkarılmıştır. Yükseklik/genişlik oranı fazla olan bölgeler de
görüntüden silinmiştir. Morfolojik işlemlerden biri olan kapama işlemi ile
paranşim hücreleri birleştirilerek öz ışınları bulunmuştur. Birleşmeyen ve öz
ışını olamayan bölgeler silinmiştir. 
Genişleme ve doldurma işlemi ile öz ışınların
son şekli belirlenmiştir. Elde edilen sonuçlar görsel ve istatistiksel olarak
verilmiştir. Yapılan analiz sonucunda; en fazla ve en az öz ışını sırasıyla
Ulmus scabra Mill. ve Abies alba Mill. de tespit edilmiştir. Belirlenmek
istenen yapıya uygun görüntü işleme tekniklerinden faydalanılarak öz ışınları
otomatik olarak bulan sistemler, odun anatomisi çalışmalarının kısa sürede ve
daha kolay bir şekilde yapılmasını sağlamaktadır.
