Detailed Description

Calulates simpel shape-related features.

This class can be used to calculate simple, shape-related features describing a given segmentation. There are no parameters that can be externaly set.

This feature calculator is activated by the option "<b>-volume</b>" or "<b>-vol</b>"

The features are calculated based on a mask. It is assumed that the mask is of the type of an unsigned short image and all voxels with an value larger or equal to one are treated as masked. (Standard MITK mask)

Some of the features are calculated twice using different methods. For voxel- based approaches, the corresponding parameter is calcualted using the voxel, for example the volume is then calculated by multiplying the volume of a single volume with the number of voxels in the mask. In the second method, the mesh based appraoch, a mesh is created prior to the feature calculation which is then done using the features.

Another difference between two features might be the evaluation of invalid values within the image. There are two possibilities: By default, only those voxels are used with an valid intensity value, i.e. where the value is not infinite or NaN. The second possibility is not correcting for these voxels and only looking at the mask. Features that use these method are marked as "(uncorrected)"

The resulting features are:

• Volumetric Features:: Voxel Volume: \( V_{single\_voxel} \) , the volume of an single volume, calculated as the multiplication of the voxel spacing in all directions.
• Volumetric Features:: Volume (voxel based): \( V_{voxel} \), the volume of the masked area. Calulated by multiplying the numer of voxels with the Voxel Volume.
• Volumetric Features:: Volume (mesh based): \( V_{shape} \), The volume based on the mesh-representation of the mask.
• Volumetric Features:: Surface (voxel based): \( A_{voxel} \), the surface of the given mask. It is calulated by summing the surfaces between a masked and an unmasked voxel.
• Volumetric Features:: Surface (mesh based): \( A_{mesh} \), the surface of the given mask calculated using the mask representation
• Volumetric Features:: Surface to volume ration (voxel based): The ratio between voxel based surface and voxel based volume given as:

  \[ F_{av\_voxel}=\frac{A_{voxel}}{V_{voxel}} \]

• Volumetric Features:: Surface to volume ration (mesh based): The ratio between voxel based surface and voxel based volume given as:

  \[ F_{av\_mesh}=\frac{A_{mesh}}{V_{mesh}} \]

• Volumetric Features:: Compactness 1 (voxel based):
• Volumetric Features:: Compactness 1 (mesh based): The compatness is a measure how spheric a shape is given. Compactness 1 is defined as:

  \[ F_{compactness\_1} = \frac{V}{\pi^{1/2} A^{3/2}}\]

• Volumetric Features:: Compactness 1 old (voxel based):
• Volumetric Features:: Compactness 1 old (mesh based): Some implementations use a slightly different definition of compactness 1. Although this is most likely an error and leads to an non-dimensionless feature, this defition is still calculated as:

  \[ F_{compactness\_1\_old} = \frac{V}{\pi^{1/2} A^{2/3}}\]

• Volumetric Features:: Compactness 2 (voxel based):
• Volumetric Features:: Compactness 2 (mesh based): The compatness is a measure how spheric a shape is given. Compactness 2 is defined as:

  \[ F_{compactness\_1} = 36 \pi \frac{V^2}{A^3}\]

• Volumetric Features::Sphericity (voxel based):
• Volumetric Features::Sphericity (mesh based): Sphericity is measure of how sphere-like a shape is:

  \[ F_{sphericity} = \frac{(36 \pi V^2)^{1/3}}{A} \]

• Volumetric Features::Asphericity (voxel based):
• Volumetric Features::Asphericity (mesh based): Sphericity is measure of how sphere-like a shape is:

  \[ F_{asphericity} = \left(\frac{1}{36 \pi }\frac{(A^3}{V^2}\right)^{1/3} - 1 \]

• Volumetric Features::Spherical disproportion (voxel based):
• Volumetric Features::Spherical disproportion (mesh based): Sphericity is measure of how sphere-like a shape is:

  \[ F_{spherical\_disproportion} = \frac{A}{4\pi R^2}= \frac{A}{\left(36\pi V^2\right)^{1/3}} \]

• Volumetric Features:: Maximum 3D diameter: This is the largest distance between the centers of two voxels that are masked.
• Volumetric Features::Bounding box volume: The bounding box volume is the volume of the smallest axis-aligned box that encapuslates all voxel centres.
• Volumetric Features::Centre of mass shift:
• Volumetric Features::Centre of mass shift (uncorrected): This is the distance between two centres of mass, namely the geometric centre and the weighted centre. The geometric centre is the mean position of all masked voxels, and the weighted centre is the mean position if the position of each voxel is weighted according to its intensity.
• Volumetric Features::PCA Major Axis length:
• Volumetric Features::PCA Major Axis length (uncorrected): A Principal component analysis (PCA) of the masekd voxel positions will give the main orientation and elongation of the masked area. The resulting eigenvectors of the PCA are sorted so that \( \lambda_{major}\geq \lambda_{minor} \geq \lambda_{least}\). The major axis length is defined as:

  \[ F_{pca\_major} = 4 \sqrt{\lambda_{major}} \]

• Volumetric Features::PCA Minor axis length:
• Volumetric Features::PCA Minor axis length: The Minor axis length is defined as:

  \[ F_{pca\_minor} = 4 \sqrt{\lambda_{minor}} \]

• Volumetric Features::PCA Least axis length:
• Volumetric Features::PCA Least axis length: The Minor axis length is defined as:

  \[ F_{pca\_Least} = 4 \sqrt{\lambda_{Least}} \]
