DETERMINATION OF HOMOGENE RAYS WITH MORPHOLOGICAL PROCESSES IN HARDWOOD AND SOFTWOOD

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.
