All the features namely maximum length of detected edges, the ratio major and minor axis
, number of pixels, maximum convolution, and the number of intersection was used as an input parameters to develop a new prediction model as shown in figure (13).
After getting the boundary of the selected region, properties such as area, perimeter, major and minor axis
The calculation results when the diameter of the probe's minor axis
was 5 cm are shown in Figure 3.
Considering the effect of the surface tension on the cross section shape deformation, the radial pressure difference between major axis a and minor axis
b during spinning process can be expressed as :
2] and the major to minor axis
ratio X in the yrast SD bands for even-even [sup.
The one way ANOVA results from Table 1 indicated that there were significant difference in term of mean values of seeds length, width, rectangular aspect ratio, major axis length, minor axis
length, and aspect ratio among the weedy rice seeds variants.
s] are the standard deviation of the major axis and the minor axis
of the ellipse, they equal to half length of major axis and minor axis
Identification was made according totwenty-four color features (Rm Gm Bm Hm Sm VmYm Cbm Crm I1m I2m I3m Rd Gd Bd Hd Sd VdYd Cbd Crd I1d I2d and I3d) 11 morphological features(Area (A) Perimeter (P) Major axis length (L) Minoraxis length (l) Aspect ratio (K) Equivalent diameter (Ed) Convex area (C) Solidity (S) Extent (Ex) Roundness (R) and Compactness (CO)) that were extracted from images of grain varieties using features such as area perimeter major and minor axis
length computed on a binary image using MATLAB 7.
As mentioned earlier in the text, the distance transform only gives us the minor axis
value in the case of non-circular cross section.
i] = [pi]/4 is chosen so that we are using a section centered on the minor axis
of the ellipsoid with a = R and b = Rcos [[theta].
a] and a minor axis
(along x axis) of R is centered at the original point of the coordinate system.
However, if the minor axis
is horizontal, it is referred to as an oblate ellipsoid.
