Fig. 10From: Sky-canopy border length, exposure and thresholding influence accuracy of hemispherical photography for complex plant canopiesEffects of the mixed-pixel zone length (i.e. pixel fraction of mixed-pixel zone), canopy gap fraction and the ETM extent on the HP estimation derived from real CHPs taken in 46 locations. The unit of the exposure manipulation, thresholding manipulation and ETM extent is stopBack to article page
