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
