Class C1DFilterKernel

put the convolution into this class, problem: it must work for all data types but should also be virtual

Global C1DInterpolatorFactory::create (const std::vector< T > &src) const __attribute__((warn_unused_result))

this should become the work of a plug-in handler

Class C1DScalar

see if scaling can be expressed by a filter

seems like downscaling isn't done properly

Global C2DPerfusionAnalysis::set_approach (CIndepCompAnalysis::EApproach approach)

the parameter should be an enum

Class C2DPPDivcurlMatrix

Optimize like the 3D version that only stores the patch of required values instead of building the whole diagonals

Class C2DTransformation::const_iterator

this iterator shouldn't be here, but should be a separate class not bound to the 2D transformation

Class C3DTransformation::const_iterator

make position readable from outside

add iteration over sub-domains

Global C3DTransformCreator

rename this to factory

Class CCmdOptionList

the whole command line option class structure needs a code cleanup

Class CDatapool

add delete key function,

add automatic key generation

(maybe) all plugins that load data should load to the pool first to enable loading from temporarly generated data

Class CHistory

Use it.

Global create_image2d_vector (P2DImage image)

the interface that requires a vector to be passes may not be the best approach in ensures that we can also load all images from a multi-record image file type but other then that it is very inconvenient

Global cross (const T2DVector< T > &a, const T2DVector< T > &b)

Check why does it use indirection to the apply-function?

Global mean_var (ForwardIterator begin, ForwardIterator end)

could be extended to vector types

Global T3DImage< T >::get_gradient (int index) const

evil, remove it

Class TDictMap< T >

extend it to also contain help strings for each flag.

Global THistogram< Feeder >::THistogram (const THistogram< Feeder > &org, double perc)

this should actually cut of a percentage of the data and not of the bins

Global THistogram< Feeder >::value_type

change to meaningful name

Class TNonrigidRegister< dim >

the class name is misleading, depending on the given transformation, linear and non-linear registration can be achieved

Class Transformation< D, I >

the interpolator factory resp. the interpolator kernel should probably be part of the class
