Performance of the image analysis algorithms with automatically threshed spikelets. Scatter plots of manual measurements versus automatic measurements with automatically threshed spikelets using the threshing unit for the number of total spikelets and the number of filled spikelets are shown. In total, 214 Huageng 295 rice plants were used as samples in the evaluation experiment. Least squares linear regression produced the following results: (a) number of total spikelets: line of best fit: y = 0.99x+6.07, correlation coefficient r = 0.993, (b) number of filled spikelets: line of best fit: y = 0.99x+4.47, correlation coefficient r = 0.997.
