Detailed Description

Utility class for the parable-based chromaticity segmentation.

A parabolic function is defined by 3 parameters a,b and c:

Parables can be created by given parameters a,b and c or by 3 given points.

Constructor & Destructor Documentation

Parable() [1/3]

icl::core::Parable::Parable ( )

inline

create an empty parable (a=b=c=0)

Parable() [2/3]

icl::core::Parable::Parable ( float  a, float  b, float  c  )

inline

create a parable with given parameters a,b and c

Parable() [3/3]

icl::core::Parable::Parable ( utils::Point32f  p1, utils::Point32f  p2, utils::Point32f  p3  )

inline

create a parable with given 3 points

To avoid numerical problems, the x coordinates of the given points are increased by a small value (0.00000001 - 0.00000003). This is harmless, as the Parable struct is used for the ChromaWidget, where given input point are defined by relative widget coordination which much less resolution
