GPU accelerated image processing for everyone
Takes a binary image and dilates the regions using a octagon shape until they touch.
The pixels where the regions touched are afterwards returned as binary image which corresponds to the Voronoi diagram.
Availability: Available in Fiji by activating the update sites clij and clij2. This function is part of clij2_-2.5.0.1.jar.
