Measure Type :

This is an intensity measure

This measure can be used in 2d and 3d case

Measure Unit Type:

Measure GreyMoments is not associated to any unit [ipsdk::shape::analysis::eMsrUnitFormat::eMUF_NoUnit]

Measure Parameter Type :

Measure GreyMoments has no parameters

Measure Result Type :

Measure GreyMoments is associated to GreyMomentsMsrResults results

Measure Shape Requirements :

Measure GreyMoments requires row intersections from shape data

Measure Dependencies :

Measure GreyMoments depends on following measures :

Measure Mode Measure Name Measure Type Measure Parameters
eMVP_2d3d GreyBarycenter GreyBarycenter
Note
See Shape Analysis 2d for more information on general shape 2d analysis and measurement usage.
See Shape Analysis 3d for more information on general shape 3d analysis and measurement usage.

Example of Python code :

Generic example in 2d case :

import PyIPSDK
import PyIPSDK.IPSDKIPLShapeAnalysis as shapeanalysis
# Create the infoset
inMeasureInfoSet2d = PyIPSDK.createMeasureInfoSet2d()
PyIPSDK.createMeasureInfo(inMeasureInfoSet2d, "GreyMomentsMsr")
#Perform the analysis
outMeasureSet = shapeanalysis.labelAnalysis2d(inGreyImg, inLabelImg2d, inMeasureInfoSet2d)
# save results to csv format
PyIPSDK.saveCsvMeasureFile(os.path.join(tmpPath, "shape_analysis_results.csv"), outMeasureSet)
# retrieve measure results
outMsr = outMeasureSet.getMeasure("GreyMomentsMsr")
# retrieve measure values
outMsrValues = outMsr.getMeasureResult().getColl(0)
print("First label first grey moment measurement equal " + str(outMsrValues[1].getMoment(shapeanalysis.GreyMomentsData.eGreyMoment3Id.eGM3I_X0Y0Z0)))

Generic example in 3d case :

import PyIPSDK
import PyIPSDK.IPSDKIPLShapeAnalysis as shapeanalysis
# Create the infoset
inMeasureInfoSet3d = PyIPSDK.createMeasureInfoSet3d()
PyIPSDK.createMeasureInfo(inMeasureInfoSet3d, "GreyMomentsMsr")
#Perform the analysis
outMeasureSet = shapeanalysis.labelAnalysis3d(inGreyImg, inLabelImg, inMeasureInfoSet3d)
# save results to csv format
PyIPSDK.saveCsvMeasureFile(os.path.join(tmpPath, "shape_analysis_results.csv"), outMeasureSet)
# retrieve measure results
outMsr = outMeasureSet.getMeasure("GreyMomentsMsr")
# retrieve measure values
outMsrValues = outMsr.getMeasureResult().getColl(0)
print("First label (X0, Y0, Z0) moment measurement equal " + str(outMsrValues[1].getMoment(shapeanalysis.GreyMomentsData.eGreyMoment3Id.eGM3I_X0Y0Z0)))

Code Example

// opening grey level input image
ImagePtr pInGreyImg2d = loadTiffImageFile(inputGreyImgPath);
// read entity shape 2d collection used for processing
Shape2dCollPtr pShape2dColl = boost::make_shared<Shape2dColl>();
IPSDK_REQUIRE(readFromXmlFile(inputShape2dCollPath, *pShape2dColl) == true);
// define a measure info set
MeasureInfoSetPtr pMeasureInfoSet = MeasureInfoSet::create2dInstance();
createMeasureInfo(pMeasureInfoSet, "GreyMomentsMsr");
// compute measure on shape 2d collection
MeasureSetPtr pOutMeasureSet = shapeAnalysis2d(pInGreyImg2d, pShape2dColl, pMeasureInfoSet);
// retrieve associated results
const MeasureConstPtr& pGreyMomentsOutMsr = pOutMeasureSet->getMeasure("GreyMomentsMsr");
const GreyMomentsMsrResults& outResults = static_cast<const GreyMomentsMsrResults&>(pGreyMomentsOutMsr->getMeasureResult());
