Detailed Description

template<class TInput, class TLabeled>
class otb::Functor::MultiScaleConvexOrConcaveDecisionRule< TInput, TLabeled >

This Functor apply a classification rule on two membership value along with two labels.

Use otb::MultiScaleConvexOrConcaveClassificationFilter to apply it image-wise.

: This algorithm is based on the following publication:

: Martino Pesaresi and Jon Alti Benediktsson, Member, IEEE: A new approach for the morphological segmentation of high resolution satellite imagery. IEEE Transactions on geoscience and remote sensing, vol. 39, NO. 2, February 2001, p. 309-320.

Given $x_1$ and $x_2$ two membership values, $L_1, L_2$ two labels associated, and $\sigma$ a tolerance value, the following decision rule is applied:

$L=\left\{\begin{array}{lcl} L_{1} &:& x_{1}>x_{2} \quad and \quad x_{1}>\sigma\\ L_{2} &:& x_{2}>x_{1} \quad and \quad x_{2}>\sigma\\ 0 &:& otherwise. \end{array}\right.$

To help the distinction between $L_{1}$ labels and $L_{2}$ , this functor adds the m_LabelSeparators value to the $L_{1}$ labels.

This functor is the decision rule used for multi-scale classification using morphological profiles.
