示例1: Process
public DetectorResult Process(Image<Bgr, byte> rawFrame, Image<Gray, byte> grayFrame)
{
grayFrame.PyrDown().PyrUp();
var processedFrame = rawFrame.Copy();
Gray cannyThreshold = new Gray(180);
Gray circleAccumulatorThreshold = new Gray(500);
CircleF[] circles = grayFrame.HoughCircles(
cannyThreshold,
circleAccumulatorThreshold,
4.0, //Resolution of the accumulator used to detect centers of the circles
15.0, //min distance
5, //min radius
0 //max radius
)[0]; //Get the circles from the first channel
foreach (CircleF circle in circles)
{
processedFrame.Draw(circle, new Bgr(Color.DarkRed), 1);
}
return new DetectorResult() {RawImage = rawFrame, GrayImage = grayFrame, ProcessedImage = processedFrame};
