“…These findings are in line with recent publication of Ma et al (2015) who also used UAS imagery. The lower overall accuracy values of the manually delineated tree crown scale (despite a lower mean area value than the OBIA 60 scale objects) can be further explained by the fact that a major part of delineated individuals in the reference dataset is actually clump of trees.…”

“…This threshold is relatively restrictive regarding to other comparable studies (60 % for Ma et al (2015) and even 50 % Stumpf and Kerle (2011)). This choice was justified because of the relatively high similarity between classes compared to these two studies (land cover classes for Ma et al (2015) and Blandslide^vs Bother objects^for Stumpf and Kerle (2011)). …”

“…An object-based image analysis (OBIA) is used for UAV image classification because the geometrical and contextual features can be incorporated into the classification [29,30]. The approach segments the UAV image into ecological patches, is combined with a decision tree model at the object level, and is able to improve the classification accuracy.…”

“…In [34] they said that "GEOBIA is a systematic framework for geographic object identification, which combines pixels with the same semantic information into an object, thereby generating an integrated geographic object." GEOBIA is a newly developed area of Geographic Information Science and remote sensing in which the automatic segmentation of images into objects of similar spectral, temporal and spatial characteristics is carried out [35].…”
