create an overlap labels layer from two labels layers


This plugin takes two labels layers (layerA, layerB) as inputs, and generate the overlapped regions as a binary labels layer. Three modes:
(1) A_OR_B: new layer = layerA OR layerB (union)
(2) A_AND_B: new layer = layerA AND layerB (intersection)
(3) A_OUTSIDE_B: new layer = layerA OUTSIDE layerB (complement)



  • Object colocalization
  • Merge separately identified objects

Future work

  • Support N labels layers
  • Basic coloc stats (% volume overlap)
  • Output Labels with distinct IDs and links to original label IDs

Release log
