Geometric Parameters of Wheat Grain Determined by Image Analysis and FEM Approach
Original language description
Digital image analysis was used to test the quality parameters of six varieties of Triticum aestivum L. and one variety of Triticum duro-compactum L. - projected area, equivalent diameter, MaxFeret and MinFeret (minimum or maximum perpendicular distancebetween parallel tangents touching opposite sides of the profile of the chosen object), perimeter, thickness and crease depth (both measured using a digital calliper) of a kernel ranging from 16.52 - 20.22 mm2, 4.58 - 5.07 mm, 16.70 - 20.82 mm, 6.21 - 7.29 mm, 3.32 - 3.78 mm, 2.69 - 3.12 mm, 0.23 - 0.42 mm. The size data were used for calculation of volumes and surface areas of wheat kernels modelled as a general ellipsoid. The calculation of surface area using finite element method (FEM) was based on computer software MAPLE 9.0 and the results were compared with a simplified method. The volumes of kernels from the ellipsoid model were corrected with consideration of measured average crease depth; the difference was then max. 3.6 %. We
