void JunctionDetector::detectJunctions ( const QImage &  image, const QImage &  cannyEdgeImage, const QImage &  gradientImage, QImage &  junctionImage, QImage &  outputJunctionImage  )

static

Detect junctions in an image. This method computes the junctions in an image using the images gradient fields and canny edges.

Parameters

image	The original image used to compute junctions.
cannyEdgeImage	The image in which the canny edges are drawn (R, G, B = 255, 0, 0).
gradientImage	The image in which the gradients are drawn (R, G = gradient vector, B = magnitude).
junctionImage	In this image the calculated junctions are drawn (R, G, B = 0, 255, 0).
outputJunctionImage	In this image, the junctions are marked.

void JunctionDetector::detectXJunctions ( QImage &  image, QImage &  junctionImage, QImage &  outputXJunctionImage, std::vector< std::vector< float >> &  luminances  )

static

Detect X-junctions of an image. This method calculates the X-junctions from an image and stores them in another image. It also returns the surrounding luminances of an X-junction.

Parameters

image	The original image used to calculate the X-junctions.
junctionImage	This image originally consists of all the junctions (R, G, B = 0, 255, 0) and the calculated X-junctions are drawn into it.
outputXJunctionImage	In this image, the X-junctions are marked.
luminances	Stores the surrounding 4 luminances of an detected X-junction.
