Phase 1 - Problem Identification and Architecture Discussion
  • Summary statements
  • Refined scope
  • Rules of engagement

Phase 2 - Algorithm Development and Work
Specific deliverables to be enumerated as result of Phase 1
Will likely include CTL and/or similar reference (e.g. Python), test cases (images, colour patches, measurement techniques)

  • Documentation, including:
  • detailed meeting notes
  • research/test results
  • rationale and design decisions
  • guidance/tutorials
