Fruit-shape data of 574 Chinese white olives (Q6691314)

We digitized the side profiles of 574 fruits of Canarium album (Lour.) DC., and used an explicit re-expression of Preston's equation (referred to as EPE hereinafter) to fit the planar coordinates of each fruit profile. By using the estimated parameters, we calculated the volume and surface area of each fruit. The black_white.zip file saves the black and white .bmp images at 600 dpi for the 574 fruit profiles. The edge_data.zip file includes the planar coordinates of each of the 574 fruits, and the EPE_results.csv file includes the estimated parameters and goodness-of-fit of the EPE, and the fruit surface area and volume calculated by the surface area and volume formulas of the solid of revolution based on the EPE for each fruit. In addition, the EPE_results.csv file also provided the measured volumes of 574 fruits using graduated cylinders.
