boundingCircleForContourError

public static VNCircle boundingCircleForContourError(VNContour contour,
                                                     org.moe.natj.general.ptr.Ptr<NSError> error)

Calculates a bounding circle that includes a collection of points or a VNContour object. Note that because this is based on a geometric shape the aspect ratio is important when using normalized points. This takes the aspect ratio of the contour into account when using a VNContour as an input. boundingCircleForPoints and boundingCircleForSIMDPoints assume that the aspect ratio is correctly applied to the points.

Parameters:

contour - A contour around which to find the bounding circle.

points - A collection of points around which to find the bounding circle.

pointCount - Number of points in points

contour - VNContour object whose bounding circle needs to be calculated

error - An output parameter, populated only in case of algorithmic failure

Returns:

the VNCircle object describing the bounding circle or nil, if the algorithm failed. The latter case is accompanied by populating an 'error' output parameter

boundingCircleForPointsError

public static VNCircle boundingCircleForPointsError(NSArray<? extends VNPoint> points,
                                                    org.moe.natj.general.ptr.Ptr<NSError> error)

calculateAreaForContourOrientedAreaError

public static boolean calculateAreaForContourOrientedAreaError(org.moe.natj.general.ptr.DoublePtr area,
                                                               VNContour contour,
                                                               boolean orientedArea,
                                                               org.moe.natj.general.ptr.Ptr<NSError> error)

Calculates a closed contour area using Green's theorem. The contour is represented by a set of points in VNContour object, It's important to note that a random set of points, or a contour with self-crossing edges will likely produce undefined results Note that because this is based on a geometric shape the aspect ratio is important when using normalized points. This takes the aspect ratio of the contour into account when using a VNContour as an input.

Parameters:

area - Output parameter to be populated with calculated contour area

contour - A VNContour object whose area is being calculated

orientedArea - If true, returns signed area - positive for CCW oriented contours and negative for CW oriented contours. If false, returned area is always positive.

error - An output parameter, populated only in case of algorithmic failure

Returns:

Area calculation status, YES indicates success, NO - failure. The failure case is accompanied by populating an 'error' output parameter

calculatePerimeterForContourError

public static boolean calculatePerimeterForContourError(org.moe.natj.general.ptr.DoublePtr perimeter,
                                                        VNContour contour,
                                                        org.moe.natj.general.ptr.Ptr<NSError> error)

Calculates perimeter, or a sum of all arc-lengths (edges), of a closed contour. The contour is represented by a set of points in VNContour object. Note that because this is based on a geometric shape the aspect ratio is important when using normalized points. This takes the aspect ratio of the contour into account when using a VNContour as an input.

Parameters:

perimeter - Output parameter to be populated with calculated contour perimeter

contour - A VNContour object whose perimeter is being calculated

error - An output parameter, populated only in case of algorithmic failure

Returns:

Perimeter calculation status, YES indicates success, NO - failure. The failure case is accompanied by populating an 'error' output parameter
