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 :

    # 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);

    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);
