General Presentation State

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
