pass()

template<class ImageWindow , class LabelsWindow , class Label , class IsBg >

static void nav2_costmap_2d::imgproc_impl::ProcessPixel< ConnectivityType::Way8 >::pass ( ImageWindow &  image, LabelsWindow &  label, EquivalenceLabelTrees< Label > &  eq_trees, IsBg &&  is_bg  )

inlinestatic

Set the label of the current pixel image.e() based on labels in its neighborhood.

Template Parameters

ImageWindow	Window parameterized by class DoNothing or ReplaceToZero
LabelsWindow	Window parameterized by class DoNothing or ReplaceToZero
Label	integer type of label

Parameters

image	input image window. Image data will not be changed. De facto, image is a const ref
label	output label window
eq_trees	union-find structure

Exceptions

LabelOverflow

if all possible labels already used
