Description
Return annotation intersection-over-union from paired flags.
Oral-health records may contain surface identifiers, annotation support, inventory or image calibration. Local count and balance rules do not verify observations, define an appropriate hygiene practice or establish a dental diagnosis.
Return annotation intersection-over-union from paired flags.
When to use this tool
Use Plaque Annotation Overlap Share when checking the stated oral-health record or measurement convention.
How to use the tool and how it works
- Enter first, second. Keep parallel arrays aligned. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read overlap, union, share, defined. Inspect defined before interpreting the associated values.
Return annotation intersection-over-union from paired flags. Require equal lengths; count both-true overlap and either-true union; share = overlap/union when positive, otherwise zero and defined = false.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| first | First | Required. Array of boolean; maximum items 256. |
| second | Second | Required. Array of boolean; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| overlap | Overlap | Required. Safe integer. |
| union | Union | Required. Safe integer. |
| share | Dimensionless ratio on the explicitly stated numerator and denominator basis. | Required. Finite number. |
| defined | Whether the stated denominator is nonzero; inspect this before using the associated ratio. | Required. Boolean. |

}Limitations and assumptions
- This compares supplied annotations, not plaque detection, clinical significance or rater reliability.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Use the relevant charting protocol and professional dental guidance for clinical interpretation, care and individual recommendations.
