Member Enumeration Documentation

template<class V >

anonymous enum

Size of the processing block (volume window).

The input volume is divided into smaller blocks - cubes for the processing.

• This is used to reduce amount of the memory required by the filtering.

Enumerator:

BLOCK_SIZE

template<class V >

anonymous enum

Maximal value stored in the internal lookup table.

Enumerator:

MAX_LUT

template<class V >

anonymous enum

Size of the internal lookup table.

Enumerator:

LUT_SIZE

template<class V >

anonymous enum

Threshold used to suppress non-corner points.

Enumerator:

DIFF_THRESHOLD

template<class V >

anonymous enum [inherited]

Check that V is volume.

You will see name of this enum somewhere in compiler error message if the type V is not volume.

Enumerator:

TEMPLATE_PARAMETER_IS_NOT_VOLUME
