Moments012Perd2C()

Moments012Perd2C(const Moments012Perd2C & momP)

Moments012Perd2C(const BoundaryC & boundary)

Gets moments 00, 10, 01, 20, 11, 22 and perimeter of the region which is determined by the 'boundary'. The moments are computed according to the origin of the coordinate system of boundary vertexes

IntT Perimeter() const

IntT & Perimeter()

RealT Compactness() const

Returns the number that express how the space of the 2d object is close to a circle. The most compact region in a Euclidian space is a circle. The returned value for a circle is 1. If the object is not compact returned value are closer to 0.

istream & operator>>(istream & is,Moments012Perd2C & mom)

void AddPixel(const PixelC & pxl)

Adds a pixel to the object and updates sums.

Moments012d2C & Centerlize()

Recomputes the moments according to the centroid.

Moments012d2C & ToPrincipalAxis()

Recomputes the moments according to the principal axis.
It is supposed that input moments are centerlized

RealT & M02()

AreaT Area() const

Returns the moment m00, ie the area of the 2 dimensional object.

RealT CentroidX() const

Returns the x co-ordinate of the centroid.
The M00 moment must be different 0.

RealT CentroidY() const

Returns the y co-ordinate of the centroid.
The M00 moment must be different 0.

RealT Elongatedness() const

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. Is is assumed that input moments are centeralized and rotated to the principal axes.
