public abstract class ImagePyramidBase<T extends ImageGray> extends java.lang.Object implements ImagePyramid<T>
Base class for image pyramids. Provides common functionality and data structures. The scale
is defined in its children PyramidDiscrete and PyramidFloat. This allows
it to be either integer or floating point and strongly typed.
When updating the pyramid, if the top most layer is at the same resolution as the original image then a reference can optionally be saved, avoiding an unnecessary image copy. This is done by setting the saveOriginalReference to true.
