  • Data licensing
  • Data Curation
  • Associating publications with the data in the database
  • Comparison of segmentations
  • What MIDAS instance to use ?
  • How much data ?
    • A dozen items..
    • About 100Gb per item
    • Suggestion:
      • Per dataset have three tiers:
        1. Testing data (data freely available, annotations/truth sequestered)
        2. Training data (data and annoations freely available)
        3. Small sample for quick evaluation
      • Provide an online viewing tool (MIDAS/DJ Viewer)
  • Data Transfer
    • Using MIDAS CPP ?
    • 100 Gbit /s Transfer rate at Kitware KHQ (about 10 GigaByte/s)
    • Use Amazon S3 Store
      • Rates and prices prohibitive
  • Scoring Algorithms
    • Client Side and Server Side the same
    • Fully open-source
    • Provided as
      1. ITK classes
      2. GenerateCLP Executables for use with BatchMake
        • How are these distributed? New toolkit?
    • Batchmake scripts provided to show how to run methods and score on a collection of data
        • How are these distributed? New toolkit?
  • Representations for
    • Tracks (3D + t)
    • Object Ids
    • Use ITK SpatialObjects ?
      • 3D + time ?
    • Use itk::LabelMaps to represent segmentations and tracks

Tracking Evaluation

  • ICCV paper: Tracking performance evaluation
  • Sometimes the data start from meshes
    • Sometimes it starts from images
    • Sometimes it starts from tracks
  • If adopting a file format for storing this data
    • THEM we must provide a library (IO API) for reading and writing this data.
    • Maybe use the MetaImage library ?
      • It already has the concepts of "polylines" and "tubes"

Server Side Processing

WARNING: THIS IS BRAINSTORMING...but we need to do something like this!

  • Rationale: The data is too large to download
    • Users could upload
      • Source code
      • Binaries
      • Virtual Machines
    • These code/binaries will be executed on the data and the output will go to the evaluation.
