Fits a contour with an ellipse.
Reference to the image containing a contour.
Acceptable distance, in pixels, that a point determined to belong to the ellipse can be from the perimeter of the ellipse.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Reference to the image containing a contour.
Best-fit ellipse.
Coordinates of the center of the ellipse.
Orientation of the major axis with respect to the horizontal.
Length of the semi-major axis.
Length of the semi-minor axis.
First angle of the circular strip.
The angle is measured counterclockwise from the x-axis of a coordinate system centered on the center of the ellipse.
Second angle of the circular strip.
The angle is measured counterclockwise from the x-axis of a coordinate system centered on the center of the ellipse.
