◆ BlobMinMomentAxisAngle

double BlobMinMomentAxisAngle
get

Returns the angle of the minimum moment of inertia.

\a InertiaMinAngle is the angle in radians (-p...p) that the axis of the minimum moment of inertia encloses together 
with the x-axis. This parameter is frequently used as a measure for the orientation of an object. The axis always runs through 
the centre of gravity of the area.

There are objects - for example circles - which do not have any pronounced direction of this axis. However, Blob also returns an angle for these 
objects because sampling effects and the representation of objects in a digital raster also result in a certain angle for a circle. 
This value is only relevant if, for example, the \a InertiaRatio parameter shows a significant difference between the minimum and maximum moments of inertia. 
This angle depends very much on quantisation and noise effects.

Furthermore, there are objects which have multiple axes of inertia which are of equal weight (e.g., the letter M). Which angle is calculated here again depends 
on quantisation and noise effects. If several identical objects exist in an image, this angle may still assume different values.

\a IntertiaMinAngle is calculated from the central moments:
<img class="ToDisplay" src="InertiaMinAngle.PNG" align="left"  alt="Angle of the minimum moment of inertia">\n\n\n\n
Another way of interpreting this angle is to imagine every image point of an object as an independent point on the XY plane. 
If a straight line is fitted to this distribution of points by the least squares method, this line runs through the centre of gravity of 
the area (\a CogX, \a CogY), and has the angle \a InertiaMinAngle to the x-axis.

◆ BlobPerimConvexPerimRatio

double BlobPerimConvexPerimRatio
get

Returns the ratio of perimeter to convex perimeter.

Blob projects every object on to the x-axis at different angles. #ConvexProjections specifies the number of projections. 
The bounding box provides the projections for 0 degree and 90 degrees (projection on to y- and x-axes). Later, the projection diameter or calliper 
diameter is calculated from these projections for every angle. This supplies information on the orthogonal extent of the object in 
relation to the direction of projection.

The <b>convex perimeter</b> of the object can be calculated from the projections later. This is approximated by a polygon that consists of the individual projection parts. 
Calculation of the convex perimeter of an object is normally very compute-intensive.
