IqmOpFracPyramid (IQM - Standard Image Operator Bundle 3.3 API)

java.lang.Object
- at.mug.iqm.api.operator.AbstractOperator
- - at.mug.iqm.img.bundle.op.IqmOpFracPyramid

All Implemented Interfaces:

IProgressEmitter, ICancelable, IOperator
```
public class IqmOpFracPyramid
extends AbstractOperator
```
2010 03 added grey value image support, Surface is calculated according to Chinga etal. J Microsc. 227 2007 not sure if it works properly!!!
2011 01 bug fix for binary images. Condition for filteredsubsample : resizing previously resized image
2011 01 added 16 bit support
2011 02 added regression data to table
2011 02 removing ModelListener extremely speeds up model configuration (adding columns, writing data,...)
2011 03 created separate method for estimation of surface area (Gradient method according to Chinga)
2011 03 added Blanket method for estimation of surface area (Blanket method according to Tang, Tao, Lam PattRec 2002, 35 1071-1081)
2011 05 added Allometric scaling (variance in dependence on the mean) according to B. West
2015 03 updated Gradient Method (Chinga) for FD estimation of grey value surfaces, coefficients of kernels have to include scale
2016 01 updated PGM (Pyramidal Gradient Method) + added PDM, both for FD estimation of grey value surfaces

Since:: 2009 07
