Detailed Description

template<class T>
class MPIScaledImage< T >

The elements of an MPIImagePyramid, a container class who's iterator steps through all the subwindows in the image at the given scale.

Generated by dereferencing an MPIImagePyramid<T>::iterator, conceptually it is the container for all of the subwindows of the image at a particular scale in the image pyramid. Typically, one iterates through each window and performs some computation using the pixels in that window. If the results are stored into another image, then this can be conceptualized as a convolution.
