The effect of segmentation parameters on extracting the crown area of Tehran pine trees (Pinus eldarica)

Abstract

Man_made forests have been created with ecological goals such as preserving water and soil resources and economic goals such as wood production. These forests help reduce pressure on natural forests. Therefore, knowledge of the state of quantitative and qualitative features of the forest has always been of interest to the managers of these types of forests and to help them in future planning and achieving primary goals. The purpose of this research is to compare the crown area of Eldarica pine trees in Pardisan Park, North Khorasan province with the change of density parameters in stages 0.1, 0.3, 0.5, 0.7, 0.9, 1 , scale in stages 0.1,0.5,0.7,0.9 and Shape in stages 25, 50, 100 ,150. The results showed that the change in each of the parameters brings different results in the estimation of the tree's crown surface. Also, the results showed that the best result was obtained in (density=0.5, scale=25, shape=0.1) and the worst result in (shape=0.9, compactness=0.1, scale=150).
