Processing Details
Preprocessing
  1. WBPP for calibration
  2. SubframeSelector
  3. ImageRegistration
  4. ImageIntegration
  5. DrizzleIntegration (Scale=2.0 / VarK=1.5)


Linear (on each channel)
  1. DynamicCrop
  2. DBE
  3. Deconvolution
  4. IntegerResample (Downsample 2x)
  5. TGVDenoise
  6. MultiscaleMedianTransform for noise reduction
