描述
union_straight_contours_histo_xldunion_straight_contours_histo_xldUnionStraightContoursHistoXldUnionStraightContoursHistoXldUnionStraightContoursHistoXldunion_straight_contours_histo_xld merges neighboring XLD
contours ContoursContoursContoursContourscontourscontours if certain criteria are fulfilled.
The maximum and minimum distances of the contours to a given
reference line are calculated. From this distances a histogram is
created. If the histogram should be smoothed, FilterSizeFilterSizeFilterSizeFilterSizefilterSizefilter_size
must be greater than one. Afterwards, the resulting histogram is
divided into ranges (from minima to minima). Contours which lie in
the same range are concatenated to a new contour. If the width of
the range is greater than MaxWidthMaxWidthMaxWidthMaxWidthmaxWidthmax_width, all contours in this range
are ignored (removed). If a contour lies in two ranges or more it is
ignored, too. If there are parallel contours, there is a
risk of merging neighboring contours.
The parameters of the regression lines are calculated newly for merged
contours.
The resulting contours cannot be displayed.
注意
Before the contour parameters can be returned by
union_straight_contours_histo_xldunion_straight_contours_histo_xldUnionStraightContoursHistoXldUnionStraightContoursHistoXldUnionStraightContoursHistoXldunion_straight_contours_histo_xld, the parameters of the regression
line to the contour must be calculated by calling
regress_contours_xldregress_contours_xldRegressContoursXldRegressContoursXldRegressContoursXldregress_contours_xld。Note further that already closed contours are
not considered for a union anymore.
