2
Video Filtering
  • Optimal Approach
  • adaptive 3-D spatial temporal filter
  • Complexity
  • Proposed Solution for real time implementation
  • Independent processing in temporal domain

3
Assumptions
  • The process model
  • s(k1)a.s(k)w(k)
  • a is constant
  • w(k) is process noise, xero mean Gaussian random
    process
  • x(k)s(k)v(k)
  • v(k) is additive zero mean Gaussian white noise

Conclusions
  • Independent processing of image-sequences in
    spatial temporal domains
  • Simple effective in perfomance
  • Using Kalman filter algorithm with pre-spatially
    non-linear filtered frames.
  • Adaptive filter easily implemented in HW
