Detailed Description

Calculates features based on the co-occurrence matrix.

The co-occurrence matrix describes the relations between voxels in a specific direction. The elements \(m_{i,k} \) of the matrix count how often a voxel with the intensity \(i \) has a neighbour in a certain direction with the intensity \( k \). The direction for each matrix is given by a directed vector \( \overrightarrow{d} \).

It is important to calculate the matrices for all possible directions in order to obtain a rotation invariant feature. For the 3D case, this means that there are 26 possible directions. Using the symmetrical properties of the co-occurrence matrix, it is then possible to calculate the features in all directions looking at 13 different directions.

The standard length of the vector is 1, e.g. looking at direct neighbours. It is possible to look at more distance neighbours. This is achieved using the parameter range which defines the distance between two neighbouring voxels in number of voxels. The default value for this is 1. It can be changes using the Method SetRange() or by passing the option cooc2::range.

There are two possible ways of combining the information obtained from the multiple directions. The first option is to calculate a common matrix for all directions and then use this matrix to calculate the describing features. The second method is to calculate a matrix for each direction, obtain the features and then report the mean and standard value of these features. Both methods are calculated by this filters and reported, distinguisehd by either an "Overall" if a single matrix is used, a "Mean" for the mean Value, or an "Std.Dev." for the standard deviation.

The connected areas are based on the binned image, the binning parameters can be set via the default parameters as described in AbstractGlobalImageFeature. The intensity used for the calculation is always equal to the bin number. It is also possible to determine the dimensionality of the neighbourhood using direction-related commands as described in AbstractGlobalImageFeature. No other options are possible beside these two options.

This feature calculator is activated by the option -cooccurence2 or -cooc2.

The features are calculated based on a mask. It is assumed that the mask is of the type of an unsigned short image. All voxels with the value 1 are treated as masked.

The following features are defined. We always give the notation for the overall matrix feature although those for the mean and std.dev. are basically equal. In the name, <Range> is replace by the distance of the neighbours. For the definitions of the feature, the probability of each intensity pair (i,k) \( p_{i,k} = \frac{m_{i,k}}{\sum_i \sum_k m_{i,k}} \).

In addition, the marginal sum \( p_{i,\cdot} = p_{\cdot,k=i} = \sum_k p_{i,k} \), which is identical for both axis due to the symmetrical nature of the matrix. Furthermore, the diagonal and cross diagonal features are used:

\[ p_{i-k}(l) = \sum_i \sum_k p_{i,k} \delta(l - \| i -k \| ) \enspace \enspace l = 0, \dots, N_g -1 \]

\[ p_{i+k}(l) = \sum_i \sum_k p_{i,k} \delta(l - ( i + k ) ) \enspace \enspace l = 2, \dots, 2 N_g \]

Here, \( \delta(x) \) is the dirac function, which is one for \(x=0 \) and zero otherwise.
