Statistics

Class: NodeImageStatistics

Node Icon

Calculate statistical properties of one or more images, with option to supply one or more masks. For multiple images and masks, the statistial properties of all combinations of images and masks will be returned.

Inputs

Input

One or more images on which the statistics will be calculated. If a mask is supplied, all images and masks must have the same matrix size. If no mask is supplied, image can have different matrix sizes.

Type: Image4DFloat, Required, Multiple

Masks

On or mor masks can be supplied to define regions in which statistics will be calculated. The matrix size of the mask(s) must match the matrix size of the image(s).

Type: Image4DBool, Optional, Multiple

Outputs

Output

A data table with the statistical information selected in the settings for all inputs.

Type: DataCollection

Settings

Node

Tag Text

The name of the data. If you export the data to .xls or .csv, this will be used as the file name.

Statistics

Mean Boolean

Calculate the mean voxel value of the image, or region of the image defined by the mask.

Max Boolean

Calculate the maximum voxel value of the image, or region of the image defined by the mask.

Min Boolean

Calculate the minimum voxel value of the image, or region of the image defined by the mask.

Standard Deviation Boolean

Calculate the standard deviation of voxel values of the image, or region of the image defined by the mask.

Volume Boolean

Calculate the volume of the image, or region of the image defined by the mask.

Median Boolean

Calculate the median voxel value of the image, or region of the image defined by the mask.

Kurtosis Boolean

Calculate the kurtosis of voxel values of the image, or region of the image defined by the mask.

Skewness Boolean

Calculate the skewness of voxel values of the image, or region of the image defined by the mask.

Calculate Percentiles Boolean

Calculate the percentiles (defined below) of the image, or region of the image defined by the mask.

Percentiles Text

The percentiles to calculate if the “Calculate percentiles” option is true.
