SimpleEdgeOptions
Describes how you want the function to find edges.
Elements
| Name | Type | Description |
|---|---|---|
| type | LevelType | Determines how the function evaluates the threshold and hysteresis values. |
| threshold | int | The pixel value at which an edge occurs. |
| hysteresis | int | A value that helps determine edges in noisy images. If a pixel value crosses the given threshold value but does not exceed the value by the value of hysteresis, the function does not consider the pixel to be part of an edge. |
| process | EdgeProcess | Determines which edges the function looks for. |
| subpixel | int | Set this element to TRUE to find edges with subpixel accuracy by interpolating between points to find the crossing of the given threshold. Set this parameter to FALSE to report an edge as the point nearest the threshold crossing. |
