Comparison Workspace Features

• Focus on flexibility and customization
  1. Allow for N comparisons of datasets
  2. Allow for customizable window layout and size
  3. Allow for virtual page of infinite size
• Focus on side-by-side view
• Focus on maximizing real estate for comparison image
  • Replace 4-up view
    1. Side-by-side: two windows
    2. Overlay: one window
  • Collapsible subwindows
    1. Thumbnail viewer
    2. Comparison cart?
  • Context driven controls
    1. HUD controls overlayed over image for zoom/pan/rotate (aka: GoogleEarth^?)
• Analysis Tools?
  • Linked controls
    1. Handle different scales? (ie: 2 volumes with different sizes)
    2. Handle different data types? (ie: 2D v. 3D image / surface v. image)
  • Viewing
    1. View XY, YZ, XZ planes
    2. Pan
    3. Annotate
    4. Browse through slices
    5. Zoom
    6. Zoomify (ie: level of detail)
  • Overlay comparison

    3. Layers (aka: GoogleEarth^?)
  • Image processing
    1. Contrast control (ie: transfer function)
    2. Masking
  • Object selection (ie: click on image/surface and get properties dialog)
  • Registration
  • Computational tools (may be specific to workspace (Image Analysis/Gene Expression)
    • Volumetric comparison (Image)
