Apply Hough transform to find line segments. The current image must be a binary image (eg. the edges as a result of the Canny edge detector)

Parameters

rhoResolution
Type: System..::.Double
Distance resolution in pixel-related units.
thetaResolution

Angle resolution measured in radians
threshold
Type: System..::.Int32
A line is returned by the function if the corresponding accumulator value is greater than threshold
minLineWidth
Type: System..::.Double
Minimum width of a line
gapBetweenLines
Type: System..::.Double
Minimum gap between lines

Return Value

The line segments detected for each of the channels
