Detailed Description

template<typename TImage>
class itk::ImageRandomNonRepeatingConstIteratorWithIndex< TImage >

A multi-dimensional image iterator that visits a random set of pixels within an image region. All pixels in the image will be visited before any are repeated. A priority image may be passed to the interator which will cause it to select certain sets of pixels (those with lower priority values) before others.

This class was contributed by Rupert Brooks, McGill Centre for Intelligent Machines, Montreal, Canada. It is heavily based on the ImageRandomIterator class.

ImageRandomNonRepeatingConstIteratorWithIndex is a multi-dimensional iterator class that is templated over image type. ImageRandomNonRepeatingConstIteratorWithIndex is constrained to walk only within the specified region. When first instantiated, it creates (and stores) a random permutation of the image pixels. It then visits each pixel in the order specified by the permutation. Thus, iterator++ followed by iterator-- will end up leaving the iterator pointing at the same pixel. Furthermore, iterating from beginning to end will cover each pixel in the region exactly once.

This iterator can be passed an image the same size as the region, which specifies a priority for the pixels. Within areas of this priority image that have the same value, the pixel selection will be random. Otherwise the pixel selection will be in the order of the priority image. In the extreme, this allows the order of the pixel selection to be completely specified.

ImageRandomNonRepeatingConstIteratorWithIndex assumes a particular layout of the image data. The is arranged in a 1D array as if it were [][][][slice][row][col] with Index[0] = col, Index[1] = row, Index[2] = slice, etc.

template<typename TImage>
itk::ImageRandomNonRepeatingConstIteratorWithIndex< TImage >::ImageRandomNonRepeatingConstIteratorWithIndex ( const ImageType ptr,
const RegionType region 
)

Constructor establishes an iterator to walk a particular image and a particular region of that image.

Constructor that can be used to cast from an ImageIterator to an ImageRandomNonRepeatingConstIteratorWithIndex. Many routines return an ImageIterator but for a particular task, you may want an ImageRandomNonRepeatingConstIteratorWithIndex. Rather than provide overloaded APIs that return different types of Iterators, itk returns ImageIterators and uses constructors to cast from an ImageIterator to a ImageRandomNonRepeatingConstIteratorWithIndex.
