Cluster adjacent Vornoi polygons of same category

We have a set of points, each with (x,y) coordinates and a category C. We have built the Voronoi diagram based on these points and would now like to "cluster" adjacent polygons when they are of a particular category. Is there a ready-made algorithm…
