Detects line segments inside an image using the DetectLineSegmentsGridRansac algorithm.

Parameters:

regionSize - Size of the region considered. Try 40 and tune.

thresholdEdge - Threshold for determining which pixels belong to an edge or not. Try 30 and tune.

thresholdAngle - Tolerance in angle for allowing two edgels to be paired up, in radians. Try 2.36

connectLines - Should lines be connected and optimized.

imageType - Type of single band input image.

derivType - Image derivative type.

Returns:

Line segment detector

Detects lines using the foot of norm parametrization, see DetectLineHoughFoot. The polar parametrization is more common, but more difficult to tune.

Type Parameters:

I - Input image type.

D - Image derivative type.

Parameters:

config - Configuration for line detector. If null then default will be used.

imageType - Type of single band input image.

derivType - Image derivative type.

Returns:

Line detector.
