Measure allowing to check whether a shape has contact with image borders.

This measure allows to check whether a shape is in contact with each one of image borders.

Here is an example of result for this measure:

Generic example in 3d case :

import PyIPSDK

import PyIPSDK.IPSDKIPLShapeAnalysis as shapeanalysis

    # Create the infoset
    inMeasureInfoSet3d = PyIPSDK.createMeasureInfoSet3d()
    PyIPSDK.createMeasureInfo(inMeasureInfoSet3d, "ImageBordersContact3dMsr")
    
    #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("ImageBordersContact3dMsr")
    
    # retrieve measure values
    outMsrValues = outMsr.getMeasureResult().getColl(0)
    print("First label measurement field bTouchXStart equal " + str(outMsrValues[1].bTouchXStart))

Code Example

    // opening grey level input image
    ImagePtr pInGreyImg3d = loadTiffImageFile(inputGreyImgPath, eTiffDirectoryMode::eTDM_Volume);
    // read entity shape 3d collection used for processing
    Shape3dCollPtr pShape3dColl = boost::make_shared<Shape3dColl>();
    IPSDK_REQUIRE(readFromXmlFile(inputShape3dCollPath, *pShape3dColl) == true);
    // define a measure info set
    MeasureInfoSetPtr pMeasureInfoSet = MeasureInfoSet::create3dInstance();
    createMeasureInfo(pMeasureInfoSet, "ImageBordersContact3dMsr");
    
    // compute measure on shape 3d collection
    MeasureSetPtr pOutMeasureSet = shapeAnalysis3d(pInGreyImg3d, pShape3dColl, pMeasureInfoSet);
    // retrieve associated results
    const MeasureConstPtr& pImageBordersContact3dOutMsr = pOutMeasureSet->getMeasure("ImageBordersContact3dMsr");
    const ImageBordersContactMsrResults& outResults = static_cast<const ImageBordersContactMsrResults&>(pImageBordersContact3dOutMsr->getMeasureResult());
