EdgeOptions
Describes how you want the function to find edges.
Elements
Name | Type | Description |
---|---|---|
threshold | unsigned | 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 | unsigned | The number of pixels that the function averages to find the contrast at either side of the edge. |
steepness | unsigned | The span, in pixels, of the slope of the edge projected along the path specified by the input points. |
subpixelType | InterpolationMethod | The method for interpolating. Valid options include IMAQ_QUADRATIC and IMAQ_CUBIC_SPLINE. |
subpixelDivisions | unsigned | 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. |
