◆ BlobMaxMoment

double BlobMaxMoment

Returns the maximum moment of inertia of the blob object.

The maximum moment of inertia of the object are calculated from the second-order central moments of the object:
<img class="ToDisplay" src="FormelMaxMoments.GIF" align="left"  alt="Max moments"><p> &nbsp;</p><p> &nbsp;</p>
Attention
Select blob through the BlobIndex property before.
Parameters
[out]BlobMaxMomentMaximum moment of inertia.
Returns

Win64
Related Topics:

◆ BlobMinMoment

double BlobMinMoment
readonly

Returns the minimum moment of inertia of the blob object.

The minimum moment of inertia of the object are calculated from the second-order central moments of the object:
<img class="ToDisplay" src="FormelMinMoments.GIF" align="left"  alt="Min moments"><p> &nbsp;</p><p> &nbsp;</p>
Attention
Select blob through the BlobIndex property before.
Parameters
[out]BlobMinMomentMinimum moment of inertia.
Returns
Minimum moment of inertia.
Supported platforms:
Win32
Win64
Related Topics:
BlobMomentRatio property, BlobMinMomentAxisAngle property

◆ BlobMinMomentAxisAngle

double BlobMinMomentAxisAngle
readonly

Returns the angle of the minimum moment of inertia of the blob object.

This is the angle in radians (0...pi) at which the axis of the minimum moment of inertia crosses the center of the blob.
This parameter is frequently used as a measure for the orientation of an object.
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 as well because sampling effects and
the representation of objects in a digital raster always result in a certain angle for a circle. \n\n
Therefore this value is only relevant if the BlobMomentRatio parameter shows a significant difference between the minimum
and maximum moments of inertia. 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 quantization and noise effects. \n\n
If several identical objects exist in an image, this angle may still assume different values. \n
The BlobMinMomentAxisAngle is calculated from the central 2nd order moments:
<img class="ToDisplay" src="FormelMinMomentsAxisAngle.GIF" align="left"  alt="FormelMinMomentsAxisAngle.GIF"><p> &nbsp;</p><p> &nbsp;</p><p> &nbsp;</p>
Attention
Select blob through the BlobIndex property before.
Parameters
[out]BlobMomentRatioAngle of the minimum moment of inertia.
Returns
Angle of the minimum moment of inertia.

◆ BlobMinMomentAxisX0

readonly

X-coordinate of the start point of the minimum moment axis.

The properties \ref BlobMinMomentAxisX0, \ref BlobMinMomentAxisY0, \ref BlobMinMomentAxisX1 and \ref BlobMinMomentAxisY1
return the coordinates of the start-point and endpoint of the axis of minimum inertia of the blob.
The start- and endpoint of that axis are determined by intersecting this axis (which runs through the blob's center of gravity)
with the bounding box of the blob (so the length of the axis does not actually scale with the value of the minimum moment!).

Select blob through the BlobIndex property before.
