Detailed Description

template<class TInputImage, class TOutputPath>
class otb::ImageToEdgePathFilter< TInputImage, TOutputPath >

This filter compute the closed edge path of a labelled object in an image (for example coming from a segmentation filter). Its output is a Path.

The input image is first surrounded by a 1 pixel wide border-line using the ConstantPadImageFilter in order to deal with stuck-to-the-border objects. The padding constant is chosen as regard to the ForegroundValue (label of the object) to avoid confusion on foreground and background values.

The edge computation is divided into two steps.

First, a linear search is performed to detect a first pixel belonging to the edge of the object.

From that pixel and until the algorithm comes back to this position, the neighborhood is iteratively and clock-wise searched to detect the next pixel in the edge.

In case of linear object (in fact open edge), the algorithm will walk the object twice in opposite directions, thus producing an edge with a null surface and twice the length of the object as perimeter.

This leads to consistent result for geometric descriptors (for instance compacity).
