General Presentation State

Working Group 11

August 21-22, 2003

“[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”

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?

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?

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?)

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)

Conformance?

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

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
