Buğday Tanelerinin Bazı Fiziksel Özelliklerinin Görüntü İşleme Tekniğiyle Belirlenmesi

Bu araştırmada; ülkemizde yaygın olarak yetiştirilen bazı buğday çeşitleri tanelerinin uzunluk, genişlik, kalınlık, izdüşüm alanı, çevre, küresellik derecesi ve farklı şekil katsayıları gibi bazı fiziksel özelliklerinin görüntü işleme tekniğinden yararlanılarak belirlenmesi amaçlanmıştır. Ekmeklik ve makarnalık tipte 13 farklı buğday çeşidi seçilmiştir. % 10, % 12, % 14 tohum nem içeriklerindeki buğday taneleri; hilum ekseni yanda, hilum ekseni altta ve dik olmak üzere 3 farklı konumda kağıtlar üzerine yerleştirilerek örnekler hazırlanmıştır. Bunlar bir tarayıcıdan geçirilerek TIFF uzantılı dosyalar halinde bilgisayar ortamına aktarılmış ve “UTHSCSA Image Tool Version 3.0” görüntü işleme programıyla değerlendirilmiştir. Çalışma sonucunda; elle ve görüntü işlemeyle yapılan ölçüm sonuçları arasındaki korelasyon katsayısının yüksek olması nedeniyle buğday tanelerinin bazı fiziksel özelliklerinin belirlenmesinde görüntü işleme tekniğinden başarıyla yararlanılacağı belirlenmiştir

Determination of Some Physical Properties of Wheat Grains by Using Image Analysis

The objective of this study was to determine some physical properties such as length, width, thickness, projected area, sphericity, periphery and different shape coefficients relating to some variety of wheat grains which are widely grown in our country by using image analysis technique. Thirteen different wheat varieties which are suitable for bread and macaroni were selected. The tests were carried out at three moisture contents of 10, 12 and 14%. Wheat grains were placed on the papers at three different positions such as hilum axis at the lateral side, hilum axis at the under side and vertical. The samples were scanned and the images of samples were loaded to the computer as a TIFF file. Then the images of samples were evaluated using UTHSCSA Image Tool Version 3.0. At the end of this study, it was found high correlation between results obtained manually and image analysis. As a result, it was determined that image analysis technique could be used for the determination of some physical properties of wheat grains
