Calculates the Grey Level Distance Zone.

This class can be used to calculate Grey Level Distance Zone as presented in Thibault et al. 2014.

The basic idea behind the Grey Level Distance Zone based features is to count the connected areas with a given intensity value \(x_i\) and a given distance to the border of each segmentation \(d_i\). Several features are then calculated based on a matrix, that gives the number of occurrence for each combination of \(x_i\) and \( d_i \) as \(m_{x,d}\).

This feature calculator is activated by the option -grey-level-distance-zone or -gldz.

The connected areas are based on the binned image, the binning parameters can be set via the default parameters as described in AbstractGlobalImageFeature. 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.

The features are calculated based on a mask. It is assumed that the mask is of the type of an unsigned short image. It is expected that the image contains only voxels with value 0 and 1, of which all voxels with an value equal to one are treated as masked.

The features depend on the distance to the border of the segmentation ROI. In some cases, the border definition might be different from the definition of the masked area, for example, if small openings in the mask should not influence the distance. Due to that, it is possible to submit a second mask, named Morphological Mask to the features that is then used to calculate the distance of each voxel to border of the segmented area. The morpological mask can be either set by the function call SetMorphMask() or by the corresponding global option. (Not parsed by the filter itself, but by the command line tool).

Beside the complete matrix, which is represented by its individual elements \(m_{x,d}\), som eadditional values are used for the definition. \(N_g\) is the number of discrete grey levels, \( N_d\) the number (or maximum value) of possible distances, and \(N_s\) the total number of zones. \(m_{x,d}\) gives the number of connected areas with the discrete grey level x and distance to the boarder of d. Corresponding, \(p_{x,d} = \frac{m_{x,d}}{N_s} gives the relativ probability of this matrix cell. \) \(N_v\) is the number of voxels. In addition, the marginal sums \(m_{x,\cdot} = m_x = \sum_d m_{x,d} \) , representing the sum of all zones with a given intensity, and sums \(m_{\cdot, d} = m_d = \sum_x m_{x,d} \) , representing the sum of all zones with a given distance, are used. The distance are given as the number of voxels to the border and the voxel intensity is given as the bin number of the binned image, starting with 1.

The following features are then defined:

• Grey Level Distance Zone::Small Distance Emphasis:

  \[ \textup{Small Distance Emphasis}= \frac{1}{N_s} \sum_d \frac{m_d}{d^2} \]

• Grey Level Distance Zone::Small Distance Low Grey Level Emphasis:

  \[ \textup{Small Distance Low Grey Level Emphasis}= \frac{1}{N_s} \sum_x \sum_d \frac{ m_{x,d}}{x^2 d^2}\]

  \[ \textup{Grey Level Non-Uniformity}= \frac{1}{N_s} \sum_x m_x^2 \]

  \[ \textup{Grey Level Non-Uniformity}= \frac{1}{N_s} \sum_d m_d^2 \]

• Grey Level Distance Zone::Zone Distance Non-Uniformity Normalized:

  \[ \textup{Grey Level Non-Uniformity Normalized}= \frac{1}{N_s^2} \sum_d m_d^2 \]

• Grey Level Distance Zone::Zone Percentage: The ratio of zones to the possible zones:

  \[ \textup{Zone Percentage}= \frac{N_s}{N_v} \]

• Grey Level Distance Zone::Grey Level Mean:

  \[ \textup{Grey Level Mean}= \mu_x = \sum_x \sum_d x p_{x,d} \]
