Property Value
Type: Int32| Event Type | Reason |
|---|---|
| CogCNLSearchRunParams Changed | Fires when the high threshold is changed. The following state flag may be affected: |
| CogCNLSearchRunParams Changed | Fires when both the low and high thresholds are changed. The following state flags may be affected: |
| Exception | Condition |
|---|---|
| ArgumentException | The supplied value is less than 0 or greater than 255. |
All edges with strengths above the high threshold are included in the edge map generated from the run-time search image. All edges with strengths below the low threshold are excluded from the edge map. Edges with strengths between the thresholds are included in the edge map if they are 8-connected (vertically, horizontally, or diagonally adjacent) to another edge with a strength above the threshold, either directly or through other edges with strengths between the thresholds. This property only applies to the Nonlinear CNLPAS algorithm.
The low threshold must be less than or equal to the high threshold; if this value is set below the low threshold, the low threshold is also set to the supplied value.
Default Value: 9.0
