Detailed Description

Container for a set of LineSegment.

This class provides a simples managment of a set of LineSegment instances. Thus the very most functions just call the LineSegment function for each instance in lineSegments vector.

void jafar::lines::LineSegmentSet::assignContourPts

(

jafar::image::Image *

image

)

Call assignContourPts for all lines of lineSegments.

Call assignContourPts for all lines of lineSegments. image has to be a black and white image with contour points. For example the result of Canny edge detection (see lines::LsExtractor)
