SpokeOptions
Describes how to search for the edges.
Elements
| Name | Type | Description |
|---|---|---|
| threshold | int | Specifies the threshold value for the contrast of the edge. The function identifies only edges with a contrast greater than this value in the detection process. |
| width | int | The number of pixels that the function averages to find the contrast at either side of the edge. |
| steepness | int | The span, in pixels, of the slope of the edge projected along the path specified by the input points. |
| subsamplingRatio | double | The angle, in degrees, between each radial search line in the spoke. |
| subpixelType | InterpolationMethod | The method for interpolating. Valid options include IMAQ_QUADRATIC and IMAQ_CUBIC_SPLINE. |
| subpixelDivisions | int | The number of samples the function obtains from a pixel. For example, set subpixelDivisions to 4 to split each pixel into four subpixels. The maximum number of subpixel divisions is 12. |
