Column Descriptions

Detection & Correction Process

  • Index: Row number identifier
  • Detection Method: Method used for color checker card and patches detection
  • Detection Parameters: Parameters used in the detection process
  • Correction Method: Method used for color correction
  • Correction Parameters: Parameters used in the correction process

Images

  • Drawed Preprocessing Input/Reference: Draw visualization of preprocessing step (detection card, expected patches, etc/)
  • Color Patches - Before/After: Color patches comparison before and after correction. Outer is reference and inside is input before/after correction
  • Input/Corrected Image: Original and color-corrected images

Color Difference Metrics (ΔE CIE 2000)

  • Patch ΔE (Before): Color difference statistics between reference and input patches before correction
    • • 0-1: Not perceptible difference
    • • 1-2: Perceptible through close observation
    • • 2-10: Perceptible at a glance
    • • 10+: Clear color difference
  • Patch ΔE (After): Color difference statistics between reference and corrected patches
  • Image ΔE: Overall image color difference statistics
  • Statistics include:
    • • Minimum: Smallest color difference
    • • Maximum: Largest color difference
    • • Mean: Average color difference
    • • Standard Deviation: Variation in differences
