EULER_2D

ECCENTRICITY_2D

$\lambda_1$ and $\lambda_2$ are the covariance matrix eigenvalues.

A disk or a cross has a null eccentricity since $\lambda_1=\lambda_2$ . The eccentricity increases with the difference between the eigenvalues, and thus measures the elongation of the object. It also indicates in some cases a privileged direction, corresponding to a large eigenvalue and a small one, i.e.: $(\lambda_1-\lambda_2)^2$ has a high value, though two orthogonal privileged directions mean two large eigenvalues and a smaller difference $(\lambda_1-\lambda_2)^2$.

BOUNDARY_VOXEL_COUNT 

The perimeter measure designates the length of the object boundary.

In the continuous case, let $x(t)$ and $y(t)$ be a parametric representation of the boundary curve $\delta X$, its perimeter is thus obtained as:

\[L(X)=\int_{\delta X}\sqrt{x'^2+y'^2}dt\]

This formula has no obvious discrete equivalent, and is therefore mostly useless for our purposes. In the discrete case, the perimeter can be simply estimated as the number of points which lie on the object boundary, i.e., points with at least one zero in their neighborhood.

RUGOSITY_2D 

The factor of rugosity determines if the contour of a shape is smooth or not.

A value close to 0 represents a smooth edges particle, a value close to 1 a rough edges particle. A value of -1 is returned when the rugosity can't be computed (i.e., object made up of few pixels).

It is defined by the following formula $Ru(p)=E_{D}(Ru_{d}(p))$ where $E_{D}$ is defined as the mean operator over all the basis length $d\in [40,L/15[$, which is defined as the distance $\overline{I_{n}I_{np}}$ in figure below. $L$ is defined as the shape perimeter. $Ru_{d}(p)$ is defined as follows:

\[Ru_{d}(p) = \sum_N(ru_{n})\]

where $ru_{n} = E_{p}( sin(\varphi)cos(\theta/2) )$. $E_{p}$ is the mean operator for all the points $P$ between the basis defined by the points $I_{n}$ and $I_{np}$. The angles $\varphi$ and $\theta$ are defined as in figure below, with $\theta \geq 2.9$. If $\theta < 2.9$ the weight is counted as 0.

SYMMETRY_2D 

The measure of symmetry determines the trend of a shape to be symmetric or not.

It is close to 1 for a symmetric shape and decreases with asymmetry. It is lower to 0.5 if the gravity center is outside the particle as illustrated on the figure below. It is measured using the following formula for a particle P :

\[S(P) = \frac{1}{2}(1 + MIN_{n}(\frac{R_{min}}{R_{max}}))\]

with $R_{min} = MIN(\overline{I_{a}G_{c}},\overline{I_{b}G_{c}})$, $R_{max} = MAX(\overline{I_{a}G_{c}},\overline{I_{b}G_{c}})$ and $MIN_{n}$ the minimum value operator over all the angles $\theta_{n}\in [0,\pi[$.
