BlobCounterBaseGetBlobsEdgePoints Method

public List<IntPoint> GetBlobsEdgePoints(
	Blob blob
)

Public Function GetBlobsEdgePoints ( 
	blob As Blob
) As List(Of IntPoint)

Parameters

blob

Type: Accord.ImagingBlob
Blob to collect edge points for.

Return Value

The method scans each row and column of the blob and finds the most top/bottom/left/right points. The method returns similar result as if results of both GetBlobsLeftAndRightEdges(Blob, ListIntPoint, ListIntPoint) and GetBlobsTopAndBottomEdges(Blob, ListIntPoint, ListIntPoint) methods were combined, but each edge point occurs only once in the list.

Note
Edge points in the returned list are not ordered. This makes the list unusable for visualization with methods, which draw polygon or poly-line. But the returned list can be used with such algorithms, like convex hull search, shape analyzer, etc.
