Tcon topics 8/17/2010

• Next ITKv4 Meeting - Potentially October 4-6
• Additional Conference Calls held last week
  • SimpleITK
  • Microscopy
    • Summary: What changes to the ITK fundamentals required for large image sizes. There may be issues for video processing as well
      • How to deal with time as a dimension
      • Memory management (Streaming)
    • Possible changes to the image structure - Luis will make proposal to handle these issues and present to the group
      • Video processing may require a ring buffer structure
      • Iterators may need to be updated to avoid access to the buffer pointer
      • Possibility of using image adapters
    • Multi-resolution Images
      • Possibility of support for this at the level of the image reader (JPEG2000: support for 2D images in files)
      • Query image reader for different resolution images
    • Non-regular image spacing
      • Potential different time point for top and bottom of image
      • VTK Rectilinear grid handles this
      • What filters are required to handle non-uniform spacing. Can convolution be applied and then resample to regular spacing
      • Does this cause a data explosion
    • File formats
      • Desire for more file format support: probably would benefit from just 2-3 formats
      • 64 bit TIFF reader, Vendor specific private tags
      • Update to libTiff is required
      • Streaming support exists for Meta, VTK, MRC. ImageSeriesReader will stream slice-by-slice
  • WrapITK
• Sequestered reference applications
• Clean-up Releases
  • Currently running behind
  • Limited coverage for Windows machines on the Dashboard - Need to turn on BUILD_EXAMPLES for these machines
  • Need to updated OpenJPEG (version 2) and libTiff
• DICOM
  • Design for QR of PACS without writing to disk
    • Currently requires to locally save a copy of the file(s) before reading as an ITK image
    • How do you know what you are going to get (e.g. multi-planar scout images)
    • Create a database or data structure to present to the programmer and then create an image from the bulk data
    • What API is required to support this functionality
    • Data structure to hold information (DOM specification - Larry Tarbox from XIP - Stephen Alyward)
    • Potential to pass Metadata Dictionary
