Data from: Standardizing the protocol for hemispherical photographs: accuracy assessment of binarization algorithms

Jonas Glatthorn & Philip Beckschäfer
Hemispherical photography is a well-established method to optically assess ecological parameters related to plant canopies; e.g. information about ground-level light regimes and the distribution of foliage within the crown space. Interpreting hemispherical photographs involves classifying pixels as either sky or vegetation. A wide range of automatic thresholding or binarization algorithms exists to classify these photographs. The variety in methodology hampers ability to compare results across studies. To identify an optimal threshold selection method, this study...
