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

Cartilage thickness rendering

• 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

Planned Visualization

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. :-(
