Detailed Description

template<class V>
class mds::img::CRohrLandmarks< V >

• Volume 3D corner/landmark detector based on Rohr's 3D differential operators.
• Algorithm is partially similar to the well-known Harris image corner detector.
• Parameter V is a used volume type.

template<class V >

typedef CLandmarkDetector<V> mds::img::CRohrLandmarks< V >::base

Volume filter base.

template<class V >

typedef base::tCorners mds::img::CRohrLandmarks< V >::tCorners

Vector of found corners.

Reimplemented from mds::img::CLandmarkDetector< V >.

template<class V >

Member Enumeration Documentation

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

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
