Parameters

cannyThreshold: Type: SystemDouble
The threshold to find initial segments of strong edges
cannyThresholdLinking: Type: SystemDouble
The threshold used for edge Linking
rhoResolution: Type: SystemDouble
Distance resolution in pixel-related units.
thetaResolution: Type: SystemDouble
Angle resolution measured in radians
threshold: Type: SystemInt32
A line is returned by the function if the corresponding accumulator value is greater than threshold
minLineWidth: Type: SystemDouble
Minimum width of a line
gapBetweenLines: Type: SystemDouble
Minimum gap between lines

Return Value

Type: LineSegment2D
The line segments detected for each of the channels
