Home < 2017 Winter Project Week < Knee Cartilage Segmentation

Key Investigators

  • Hans Meine (University of Bremen, MEVIS)

Project Description

Objective Approach and Plan Progress and Next Steps
  • Segment knee bones and cartilages for cartilage thickness assessment (osteoarthritis)
  • Train network
  • Save checkpoints for nice learning animation
  • Carefully increase size of training data during training (how much data is needed?)
  • Create nice animation showing how segmentation improves with increasing number of datasets
  • Win Titan X ;-)
  • Code for special kind of training written
  • Network trained (Tue/Wed)
  • Visualization created (Wed/Thu)
  • Code for running visualization on all intermediate states written (Thu)
  • Broke remote TeamViewer connection to machine
    • completely shut out, need to cancel project until return to Bremen

Background and References

Goal / context

  •  : analysis of cartilage thickness for ostheoarthitis assessment
  • High-resolution data is from the University of Freiburg (T. Lange, K. Izadpanah)
    • patellofemoral joint (prospective motion correction)
    • depicted image is a healthy volunteer
    • cf. CARS 2016 submission

Training worked fine

Glimpse at partial animation

This is only the 2d part, I cancelled the rendering because the 3d cameras were not properly set up, and made a mistake, completely shutting myself out of remote access to the machine required for this project. :-(
