Edges
Each of the following functions references a Edges data structure as the first parameter.
Function | Description |
---|---|
Returns the Angle of the indexed edge. |
|
Returns the specified Column value from the indexed edge. Index1 selects the edge number, and Index2 specifies the point (0 = left-most point; 1 = right-most point; or 2 = mid-point). |
|
Returns the average contrast between the foreground and background (in grey levels, 0 to 255) found. Contrast is positive for black-to-white transitions, and negative for white-to-black transitions. The Edges structure must be created by a FindCircleMinMax function. |
|
Returns the distance between two edges (edge pair). The Edges structure must be created by a Caliper function. For more information, see Caliper. |
|
Returns the radius of the maximum deviation from the best edge. The Edges structure must be created by a FindCircleMinMax function. For more information, see FindCircleMinMax. |
|
Returns the radius of the minimum deviation from the best edge. The Edges structure must be created by a FindCircleMinMax function. |
|
Returns the number of edges found. |
|
Returns the region X position of the edge or the edge pair center. The Edges structure must be created by a Caliper function. |
|
Returns the Radius value from the indexed curved edge. |
|
Returns the specified Row value from the indexed edge. Index1 selects the edge number, and Index2 specifies the point (0 = top-most point; 1 = bottom-most point; or 2 = mid-point). |
|
Returns the Score value from the indexed edge. Score is positive for black-to-white transitions and negative for white-to-black transitions (except for FindSegment and FindCircleMinMax, where Score is always positive). For more information, see FindSegment. |
|
Returns the standard deviation value. The Edges structure must be created by a FindCircleMinMax function. Note: This calculation
is a biased standard deviation, where the denominator is N-1 (an unbiased
standard deviation has a denominator of N).
