Description
Sum area separately for observed and missing entries.
Counts per field or area depend on the sampled denominator and any overlap or edge policy. Scaling a sampled density assumes the counted region represents the target region.
Sum area separately for observed and missing entries.
When to use this tool
Use Micrograph Missing Field Area when you need a transparent field, grid, or area-normalized count.
How to use the tool and how it works
- Enter fieldAreas, missing. 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 observedArea, missingArea. Use the output convention below.
Require aligned nonnegative fieldAreas and missing flags. Sum area separately for observed and missing entries.1

| missing | Missing | Required. Array of boolean; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| observedArea | Observed Area | Required. Finite number. |
| missingArea | Missing Area | Required. Finite number. |

}Limitations and assumptions
- Areas must share a unit; missing-field contents and representative coverage are not inferred.
- 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.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the original images and a documented sampling and counting protocol, with uncertainty analysis where needed.
