Moments2d2C()

Default constructor
Creates the moment object with all moments set to be zero.

Moments2d2C(RealT nm00,RealT nm10,RealT nm01,RealT nm20,RealT nm11,RealT nm02)

Constructor from a set of values.

void AddPixel(const Index2dC & pxl)

Adds a pixel to the object and updates sums.

void AddPixel(const Point2dC & pxl,RealT weight = 1)

Adds a position with a weight to the object and updates sums.

const Moments2d2C & operator +=(const Index2dC & pxl)

Add pixel to set.

const Moments2d2C & operator +=(const Point2dC & point)

Add pixel to set.

Vector2dC PrincipalAxis() const

Calculate the size of the principle axis.
It returns the new values for M02 and M20, the largest is the first element of the vector.

static RealT Elongatedness(const Vector2dC & principalAxis)

Returns the ratio of the difference and the sum of moments m02 and m20.
The value 0 means that objects is a symmetrical object, the value 1 corresponds to a one-dimensional object.
