Project Description

Uncertainty-aware Information Fusion for Real-time Soft Tissue Motion Estimation. This is part of Boyan's PhD thesis.

Objective

  • Need to fuse motion prior and observations/measurements in an uncertainty-aware fashion.
  • Stochastic processes are a very nice formal mathematical framework which allows for that.
  • Estimating the motion signal value at a given location in the domain requires conditioning the motion prior on the observations.
  • The conditioning requires the inversion of an n X n matrix (n is the number of observations).
  • Time complexity O(n^3)
  • Identify appropriate formalisms and, if needed, approximation approaches to make calculations fast enough for interventional use.
