Detailed Description

This interface holds a collection of blob results.

Usually you get the LBlobResults object from the ILBlobAnalysis::Build() as analysis result. You can then use this interface to access individual result and draw the results on graphics windows.

Example Code

C++

ILBlobResultsPtr blobResults;
LPVErrorCode err = blobAna->Build(img, roi, &blobResults);
if (err != LPVErrorCode::LPVNoError) return;
int c = blobResults->Count();
for (int i = 0; i < c; ++i) {
    ILBlobPtr blob = blobResults->Item(i);
    // handle each blob result
}

C#

LBlobResults blobResults;
LPVErrorCode err = blobAna.Build(img, (LRegion)roi, out blobResults);
if (err != LPVErrorCode.LPVNoError) return;
int c = blobResults.Count();
for (int i = 0; i < c; ++i) {
    LBlob blob = blobResults.Item(i);
    // handle each line result
}

COM

ILBlobResultsPtr blobResults;
LPVErrorCode err = blobAna->Build(img, roi, &blobResults);
if (err != LPVErrorCode::LPVNoError) return;
int c = blobResults->Count();
for (int i = 0; i < c; ++i) {
    ILBlobPtr blob = blobResults->Item(i);
    // handle each blob result
}

Member Function Documentation

Add()

void Add

(

ILBlob *

blob

)

Add a blob to the collection.

Parameters

[in]

blob

The input blob object.

Draw()

void Draw	(	HDC	hdc,
		int	index,
		LPVBlobDrawFlags	drawFlags,
		double	zoomX,
