Table 7 Summary of canopy height metrics used in this study for the estimation of aboveground biomass in wheat

From: Improved estimation of aboveground biomass in wheat from RGB imagery and point cloud data acquired with a low-cost unmanned aerial vehicle system

Input variable Name Formulation
Hmean Mean height \(H_{mean} = \frac{1}{n}\mathop \sum \limits_{i = 1}^{n} h_{i}\)
Hmedian Median height \(H_{median} = median\;of\;h_{i}\)
Hpercentile Percentile height 25%, 50%, 75%, 95%
Hstd Standard deviation of height \(H_{std} = \sqrt {\frac{1}{n}\mathop \sum \limits_{i = 1}^{n} \left( {h_{i} - H_{mean} } \right)}\)
CV Coefficient of variation \({\text{CV}} = \frac{{H_{std} }}{{H_{mean} }}\)
