Validation of HTPheno. Two exemplary correlations (A, E) and the deviation of automatically obtained values from manually measured values are plotted. The values have been manually derived from the images of 8 plants: top view (A, B, C, D), side view (E, F, G) at 6 different days after sowing. The colours in the correlation diagrams (A, E) represents 6 different time points after sowing. Every bar in the deviation diagrams shows the mean deviation of the automatically obtained values from the manually obtained values for these 8 plants as black line and the interquartile range between the lower quartile and the upper quartile in green which indicate the distribution of 50 percent of the samples. Additionally the range (minimal and maximal parameter values) is given as black horizontal line.
