WebDescription¶. Extracts connected components from input segmentation label image. By default, the largest connected component is extracted. In case of extract-connected-components-output-component-labels, the labels of the components are written instead. WebConnected components Computes the connected component membership of each vertex and returns a graph with each vertex assigned a component ID. See Wikipedia for background. NOTE: With GraphFrames 0.3.0 and later releases, the default Connected Components algorithm requires setting a Spark checkpoint directory.
