Metrics

Includes filters for computing:

• Image quality measures (without reference):
  • Signal-to-Noise Ratio (SNR)
  • Contrast-to-Noise-Ratio (CNR)
  • Q Measure
• Similarity metrics
  • Peak Signal-to-Noise Ratio
  • Structural Similarity Index (SSIM)
  • Mean Absolute Error
  • Mean Squared Error (MSE)
  • Root Mean Square Error (RMSE)
  • Normalized Root Mean Square Error
  • Normalized Correlation
  • Joint Entropy (+ per-image entropy)
  • Mutual Information
  • Normalized Mutual Information
  • Equal Pixel Rate
• Segmentation quality measures (computed via ITK's LabelOverlapMeasuresImageFilter):
  • Total overlap
  • Union overlap (also known as Jaccard index)
  • Mean overlap (also known as Dice coefficient)
  • Volume similarity
