Detailed Description

This interface holds a collection of contour detection results.

Usually you get the LContourResults object from the ILContourDetector::Detect() as detection result. You can then use this interface to access individual result and draw the results on graphics windows.

Example Code

C++

ILContourResultsPtr contourResults;
LPVErrorCode err = contourDetector->Detect(img, roi, &contourResults);
if (err != LPVErrorCode::LPVNoError) return;
int c = contourResults->Count();
for (int i = 0; i < c; ++i) {
    ILContourResultPtr result = contourResults->Item(i);
    // handle each contour result
}

C#

LContourResults contourResults;
LPVErrorCode err = contourDetector.Detect(img, roi, out contourResults);
if (err != LPVErrorCode.LPVNoError) return;
int c = contourResults.Count();
for (int i = 0; i < c; ++i) {
    LContourResult result = contourResults.Item(i);
    // handle each contour result
}

COM

ILContourResultsPtr contourResults;
LPVErrorCode err = contourDetector->Detect(img, roi, &contourResults);
if (err != LPVErrorCode::LPVNoError) return;
int c = contourResults->Count();
for (int i = 0; i < c; ++i) {
    ILContourResultPtr result = contourResults->Item(i);
    // handle each contour result
}
