Fig. 6
An example of procedure for extracting ear position. a Side view image of the plant. Numbers correspond to leaf ranks and red point to the ‘ground truth’ ear position, b stem width along the stem, with alternations of low values corresponding to internodes and of peaks corresponding to leaves (numbered in red). The assumed ear position corresponds to (i) a wider internode (between leaves 10 and 11, horizontal arrow) and (ii) a clear decrease in internode width from internode 11 onwards (vertical arrow)
