Detailed Description

Base class of filters that compute a near-optimal intrinsic surface map

Surface map filters of this type find the optimal affine combination weights of independently computed conformal and authalic surface maps with given fixed boundary values which minimize a certain non-linear distortion criterion.

ComputeLambda()

virtual double mirtk::NearOptimalIntrinsicSurfaceMapper::ComputeLambda ( vtkDataArray *  u0, vtkDataArray *  u1  ) const

protectedpure virtual

Compute affine combination weight that minimizes a given distortion measure

Parameters

[in]	u0	Discrete authalic surface map values, i.e., lambda=0.
[in]	u1	Discrete conformal surface map values, i.e., lambda=1.

Returns

Affine combination weight \(\lambda\), where final surface map values are computed as \(\lambda u1 + (1 - \lambda) * u0\).

Implemented in mirtk::IntrinsicLeastAreaDistortionSurfaceMapper, and mirtk::IntrinsicLeastEdgeLengthDistortionSurfaceMapper.
