image =	shapeToLabel2dImg (inLabelsShape2d)
image =	shapeToLabel2dImg (inPILabelsShape2d)

Detailed Description

algorithm allowing to create a label 2d image from a collection of shape

This algorithm allows to re-create a label image (Connected Component 2d) from a shape 2d image. Shape intersection with image rows are set with respect to shape label.

Note: if some shape intersect, intersection pixels are set to highest label value.

Here is an example of a shape to label 2d image operation :

Example of Python code :

Example imports

import PyIPSDK
import PyIPSDK.IPSDKIPLAdvancedMorphology as advmorpho
import PyIPSDK.IPSDKIPLShapeSegmentation as shapesegmentation

Code Example

    # opening of input image
    inImg = PyIPSDK.loadTiffImageFile(inputImgPath,
                                      PyIPSDK.eTiffDirectoryMode.eTDM_Volume,
                                      PyIPSDK.eTiffBufferMode.eTBM_Binary)
    
    # connected components analysis
    inLabelImg2d = advmorpho.connectedComponent2dImg(inImg)
    
    # label contour extraction computation
    outShape2dColl = shapesegmentation.labelShapeExtraction2d(inLabelImg2d)
    
    # write extracted shapes to output label image
    outLabelImg = shapesegmentation.shapeToLabel2dImg(outShape2dColl);

    // connected components analysis
    ImagePtr pInLabelImg2d = connectedComponent2dImg(pInBinImg2d);
    // extract contours from connected component (label) image
    Shape2dCollPtr pShape2dColl = labelShapeExtraction2d(pInLabelImg2d);
    // write extracted shapes to output label image
    ImagePtr pOutLabelImg = shapeToLabel2dImg(pShape2dColl);
