Calculate Root Length using Kimura's Method with optimizations
Usage
root_length(img, unit = "cm", dpi = 300, select.layer = 1)
Arguments
- img
A skeletonized root image raster
- unit
Output unit ("px" or "cm")
- dpi
Image resolution (required when unit = "cm" or "inch")
- select.layer
Integer. Specifies which layer to use if the input is a multi-band image. Default is `2`.
Value
Numeric value representing root length in specified unit
Examples
data(skl_Oulanka2023_Session01_T067)
img = terra::rast(skl_Oulanka2023_Session01_T067)
RL = root_length(img = img,unit = "cm", dpi = 300, select.layer = 2)
