  Using results from the field of robust statistics, we derive a class
  of Kalman filters that are robust to structured and unstructured
  noise in the input data stream. Each filter from this class
  maintains robust optimal estimates of the input process's hidden
  state by allowing the measurement covariance matrix to be a
  non-linear function of the prediction errors. This endows the filter
  with the ability to reject outliers in the input stream.
  Simultaneously, the filter also learns an internal model of input
  dynamics by adapting its measurement and state transition matrices
  using two additional Kalman filter-based adaptation rules.  We
  present experimental results demonstrating the efficacy of such
  filters in mediating appearance-based segmentation and recognition
  of objects and image sequences in the presence of varying degrees of
  occlusion, clutter, and noise.
