Methods
| Name | Description | |
|---|---|---|
| Angle |
Calculates angle orientation of a blob.
This function uses central moments so cvCentralMoments should have been called before for this blob. (cvAngle)
|
| CalcCentroid |
Calculates centroid.
Centroid will be returned and stored in the blob structure. (cvCentroid)
|
| Clone | |
| Equals | (Inherited from Object.) |
 | Finalize | (Inherited from Object.) |
| GetHashCode | (Inherited from Object.) |
| GetType | (Inherited from Object.) |
| MemberwiseClone | (Inherited from Object.) |
| SaveImage |
Save the image of a blob to a file.
The function uses an image (that can be the original pre-processed image or a processed one, or even the result of cvRenderBlobs, for example) and a blob structure.
Then the function saves a copy of the part of the image where the blob is.
|
| SetImageRoiToBlob |
Set the ROI of an image to the bounding box of a blob.
|
| SetMoments |
Set central/hu moments and centroid value from moment values (M**)
|
| ToString | (Inherited from Object.) |
