## Detailed Description

Calulates first order features based on a histogram.

This class can be used to calculate first order features based on a histogram. For each feature, two variations are given, once the value of the feature that is obtained if the mean intensity of the histogram bins is used and the histogram bin that corresponds to the feature value. See AbstractGlobalImageFeature for more information on the histogram initialization. The histogram gives a probability $$p_i$$ for the intensity $$x_i$$ that is linked to the bin $$i$$. The histogram bins start at index 1.

This feature calculator is activated by the option "<b>-first-order-histogram</b>" or "<b>-foh</b>". Beside the options for the histogram definitions, which are given in the description of AbstractGlobalImageFeature , no additional parameters are available.

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 of 1 are treated as masked.

The resulting features are:

• First Order Histogram::Mean Value: The mean intensity of all voxels, calulated by $$\mu_x = \sum p_i x_i$$.
• First Order Histogram::Variance Value The variance intensity is calculated as : $$\sigma^2 = \sum p_i (x_i - \mu_x)^2$$.
• First Order Histogram::Skewness Value:

$skewness = \frac{\sum p_i (x_i - \mu_x)^3}{\sigma^3}$

• First Order Histogram::Excess Kurtosis Value:

$skewness = \frac{\sum p_i (x_i - \mu_x)^4}{\sigma^4} - 3$

• First Order Histogram::Median Value: The median intensity value based on the histogram values.
• First Order Histogram::Minimum Value: The minimum observed intensity value.
• First Order Histogram::Percentile 10 Value: The intensity that is equal or greater than 10% of all observed intensities.
• First Order Histogram::Percentile 90 Value: The intensity that is equal or greater than 90% of all observed intensities.
• First Order Histogram::Maximum Value: The maximum observerd intensity value.
• First Order Histogram::Mode Value: The most common intensity value, i.e. the value of the bin with the highest probability.
• First Order Histogram::Interquantile Range Value: The intensity difference between Percentile 75% ( $$P75$$) and Percentile 25% ( $$P25$$).
• First Order Histogram::Range Value: The difference between the observed maximum and minimum intensity.
• First Order Histogram::Mean Absolute Deviation Value:

$\textup{mean absolute deviation} = \sum p_i \left \| (x_i - \mu_x) \right \|$

• First Order Histogram::Robust Mean Value: The mean of all intensities between the 10% and 90% quantile.
• First Order Histogram::Robust Mean Absolute Deviation Value: The Mean absolute deviation for all values between the 10% and 90% quantile. It is based on the robust mean value.
• First Order Histogram::Median Absolute Deviation Value:

$\textup{mean absolute deviation} = \sum p_i \left \| (x_i - \textup{median}) \right \|$

• First Order Histogram::Coefficient of Variation Value:

$\frac{\sigma_x}{\mu_x}$

• First Order Histogram::Quantile coefficient of Dispersion Value:

$\textup{Quantile coefficient of Dispersion} = \frac{P75 - P25}{P75 + P25}$

• First Order Histogram::Entropy Value: The entropy is only based on histogram bins with a probability greater than 0.0000001:

$\textup{entropy} = - \sum p_i \textup{log}_2 p_i$

• First Order Histogram::Uniformity Value: $$\sum p_i^2$$
• First Order Histogram::Mean Index: The mean index of all voxels, calulated by $$\mu_i = \sum p_i i$$.
• First Order Histogram::Variance Index: The variance index is calculated as : $$\sigma_i^2 = \sum p_i (i - \mu_i)^2$$.
• First Order Histogram::Skewness Index:

$skewness = \frac{\sum p_i (i - \mu_i)^3}{\sigma_i^3}$

• First Order Histogram::Excess Kurtosis Index:

$skewness = \frac{\sum p_i (i - \mu_i)^4}{\sigma_i^4} - 3$

• First Order Histogram::Median Index: The median index value based on the histogram values.
• First Order Histogram::Minimum Index: The index of the minimum observed intensity value.
• First Order Histogram::Percentile 10 Index: The index oft the intensity that is equal or greater than 10% of all observed intensities.
• First Order Histogram::Percentile 90 Index: The index of the intensity that is equal or greater than 90% of all observed intensities.
• First Order Histogram::Maximum Index: The index of the maximum observerd intensity value.
• First Order Histogram::Mode Index: The index of the most common intensity value, i.e. the index of the bin with the highest probability.
• First Order Histogram::Interquantile Range Index: The index difference between Percentile 75% ( $$P75$$) and Percentile 25% ( $$P25$$).
• First Order Histogram::Range Index: The index difference between the index of the observed maximum and minimum intensity.
• First Order Histogram::Mean Absolute Deviation Index:

$\textup{mean absolute deviation} = \sum p_i \left \| (i - \mu_i) \right \|$

• First Order Histogram::Robust Mean Absolute Deviation Index: The Mean absolute deviation for all values between the 10% and 90% quantile. It is based on the robust mean value.
• First Order Histogram::Median Absolute Deviation Index:

$\textup{mean absolute deviation} = \sum p_i \left \| (i - \textup{median}) \right \|$

• First Order Histogram::Coefficient of Variation Index:

$\frac{\sigma_i}{\mu_i}$

• First Order Histogram::Quantile coefficient of Dispersion Index:

$\textup{Quantile coefficient of Dispersion} = \frac{P75 - P25}{P75 + P25}$

• First Order Histogram::Entropy Index: The entropy is only based on histogram bins with a probability greater than 0.0000001: $$\textup{entropy} = - \sum p_i \textup{log}_2 p_i$$. Note that this is the same as the entropy value.
• First Order Histogram::Uniformity Index: $$\sum p_i^2$$. Note that this is the same as the uniformity value.
• First Order Histogram::Maximum Gradient: The maximum difference between the probability of three neighbouring bins. For bins at the edge of the histogram, only two bins are used for the calulation.
• First Order Histogram::Maximum Gradient Index: The index of the bin that belongs to the maximum gradient.
• First Order Histogram::Minimum Gradient: The minimum difference between the probability of three neighbouring bins. For bins at the edge of the histogram, only two bins are used for the calulation.
• First Order Histogram::Minimum Gradient Index:The index of the bin that belongs to the minimum gradient.
• First Order Histogram::Robust Mean Index: The mean index of all intensities between the 10% and 90% quantile.
• First Order Histogram::Number of Bins: The number of bins in the histogram. This is rather for control, as this parameter is likely to be determined by the configuration rather than the image.
• First Order Histogram::Bin Size: The binsize of the bins from the histogram. This is rather for control, as this parameter is likely to be determined by the configuration rather than the image.
