The amplitude of the ellipse roundness is defined as [delta] = [delta]1 + [delta]2 where [delta]1 is the distance between the major axis endpoint Ato the ideal circular profile and [delta]2 is the distance between the
minor axis endpoint B and the ideal circular profile.
Canny edge detection was used to identify features at the center of the seed namely maximum length of detected edge, ratio major and
minor axis, number of pixel, maximum convolution, and number of intersection.
The features included Perimeter, Area, Major axis length,
Minor axis length, Filled area, Orientation, Equiv diameter, Euler number, Solidity, Extent, Eccentricity and Convex Area (Russ, 1999).
0,1,0] in figure 7, also having an oblate spheroidal shape with
minor axis y.
The major and
minor axis angles (the smallest angle between the arm cranking and the major or
minor axis, respectively) were 96.
The measurements most commonly used are Feret's diameter, by calculating the major axis and the
minor axis (Zheng et al.
ellipse(81,70,16,32); // Draw the left eye with an ellipse at coordinates (x,y) = (81,70) and
minor axis of length 16 and major axis of length 32
The length of the probe's
minor axis was, respectively, at 1, 2, 4, 5, 6, 10, and 20 cm, while that of its major axis along the z-direction was 52 cm.
The basic dry-spinning equations have been developed on our previous work [16], the glass transition temperature and imidization degree of the precursor fibers are related to solvent mass fraction and curing temperature [22], and the final imidization degree of precursor fiber is taken from our experimental data [23], Here, the arithmetic mean of major axis and
minor axis are used to substitute for the fiber radius, and the profile degree equation of cross section is derived to calculate the fiber shape change.
Figure 3 shows a cross section, representing the dome of a cabochon, taken on the vertical plane of the
minor axis and parallel to the horizontally oriented fibrous inclusions or structure (hereafter termed fibres), one of which is indicated by the short black line.
If X represents the ratio between the major to
minor axis of an ellipsoid, then X can be deduced from Q by using the following formula [19]
The extraction of individual morphological characteristics of weedy rice seeds variants were carried out to extract individual seed length, width, rectangular aspect ratio, major axis length,
minor axis length and aspect ratio [3, 4].
minor axis - the shorter or shortest axis of an ellipse or ellipsoid
