3.9 Gaussian Kernel Size

  • For deformation update: Gaussian smoothing kernel size in mm to smooth the iterative update deformation field. Range of values (0-3). Higher values result in more regularized, smoother image. low values will result in less smoothing.
  • For total deformation: Increase it only if one notices salt and pepper in the structures.
  • For gradient step length: Default value is 1.5. Reduce it for finer scales and increase it for larger deformations.
  • For time domain update: Data smoothing converge over time space 't'. Default is 0.5
  • For time domain total: Total smoothing over time domain.Default is 0.1
  • Number of time points: Related to how long it will take.
