Title: General Presentation State


1
General Presentation State
  • Working Group 11
  • August 21-22, 2003

2
GSPS does not address
  • more complex presentation related issues that
    imply advanced display application functionality.
    A future supplement may cover
  • image processing
  • image segmentation
  • image registration and fusion
  • 3D display, surfaces rep., and rendering
  • cine and time based presentation of multi-frame
    images, including preferred frame rate
  • query of Display Device characteristics
  • advanced graphic annotation including complex
    objects that may be edited

3
Specific needs now
  • Include capabilities to put color images on par
    with grayscale
  • GSPS Annotation, graphics, overlay, shutter,
    reorientation, displayed area for all images
  • Color calibration define the incoming image and
    define methods for color consistency
  • Other needs?
  • Other wish list items?

4
Issues and questions (1)
  • Strictly a superset of Grayscale SPS?
  • Define Color Standard Display Function (CSDF) be
    defined, similar to DICOM Part 14?
  • Should this be a separate supplement?
  • What color spaces to support? (RBG, YBR
    variants, other?)
  • Handle different levels of the ICC standard?

5
Issues and questions (2)
  • Other new items that are needed in presentation?
  • Do we handle color images with only grayscale (US
    tag (0028, 0014) ) ? Are these to be in
    P-values?
  • Include restrictions on flipping (for 3-D?)

6
Consistency items
  • Provide grayscale consistency
  • On color display devices
  • Grayscale parts of color images (RGB YBR)
  • Hardcopy color consistency!?!
  • Define imaging chain for color
  • Do we have equivalent of P-values?
  • Do we handle conversion of color to grayscale
    (and subsequent P-value)

7
Conformance?
  • Conformance how to define for all media (or
    restrict to softcopy?

8
Tasks
  • Define the purpose and requirements of color SPS.
  • Define new attributes that must be defined
  • Define relationship with GSPS
  • Consider color consistency and how to define
  • Decide if we need Color Standar
  • References to both color and grayscale objects
  • Other items overlays (?), graphics, icons
