WebOverview For my use case, I needed to sample an image to provide a list of regions that may contain an object. One strategy is to use an over-segmented image, hierarchical merging and a similarity measure to produce a list of proposals. I required the ability to generate a RAG with node descriptions and edge weights that differed from the default … WebAug 11, 2015 · The Sunburst on the right shows fewer data labels since there is less chart real estate to display information.
