ivigraph

ivigraph and interactive version of vigranumpy with a labView-ish gui for image processing operator flow charts

Quickstart:

run flow.py and change the "lena" path to an image of your choise. Cick on Flowchart-DockArea (flowchart itself might be hidden) in the GUI and edit the graph

  • right click to add new operators
  • press "del" to remove connections and nodes
  • connect operator to one of the 4 image viewers

Dependencies:

Known Bugs:

  • ColorChannel Nodes do not work on some machines ( strage vigra c++ signature error)
  • Load:
    • one might need change the histogram range a tiny bit to refresh the image
  • Sometimes one gets floating point error when deleting edges no idea what is going on
    • (can someone reproduce this error?)
