1. Allen's presentation of plan
   • Now vs. later
     • what do we need in order to release something?
       • should at least cover most or all of BioImage functionality
       • load a data set (SR, NRRDS, Dicom, Matlab),
       • orthogonal slice view
       • change color maps
       • volume rendering, with Xfer function editor;
       • paint on slice view to change Xfer function
       • crop and reorient image data
       • resampling, histogram equalization, median filtering
       • viewing options from SR Viewer
     • BioImage is broken now
       • we need to replace all the functionality of BioImage as a minium
     • Marty's app
       • has a few things but is missing a lot
   • I/O Engine
     • use Seg3D engine (ITK)
     • verison 1.0 can be the same level of support as Seg3D
     • later, we will need to handle larger data
       • look to Numira for support on this
     • consider saving files in NRRD and read from them
     • file reading becomes mostly file conversion
   • Image processing
     • could be based on ITK
       • requires a lot of conversion at present
     • but the needs are simple enough and we have code around, we can write ourselves
       • would reduce need for conversion; stay in NRRD
       • TEEM has a lots of image processing tools too
   • GUI
     • separate GUI layer from actual application layer
     • Undo functionality
       • transfer function easy to keep some history
       • image processing hard to keep copies; one solution is to save most recent generation;
         • another solution is regenerate; save all of the operation stack
         • need to make UI to manage the command stack
         • idea: allow user to bookmark a place in a workflow that is saved in a temporary file
2. What to use from Seg3D
   • almost nothing
   • use some of SCIRun
3. Overall GUI design
   • topic for next week's meeting
