Nimage, the number of microscopic images used for individual plant family; CA, counting accuracy; CP, counting precision; SIA, stomatal index accuracy; SIP, stomatal index precision; R2 and RMSE were obtained from the simple linear regression (y = x) between manual counting by experts and automatic counting.
