Computer image analysis and physico-mechanical properties of wild sage seed (Salvia macrosiphon)

Abstract

A computer vision system was developed to evaluate the geometrical properties of small seeds and the results compared to the measurements obtained by a micrometer. The correlation found between the results of two methods for principal dimensions of wild sage seed with R2 values ranged between 0.64-0.99. Some physical properties were investigated including projected area, sphericity, roundness, surface area, unit mass, 1000 grain mass, volume, true density, bulk density and porosity. While the mechanical properties evaluated were static coefficient of friction, filling and funning angles of repose, terminal velocity and textural properties including rupture force, hardness and energy absorbed.
