Statistics
Class: NodeImageStatistics
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.
Example Workflows
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 per Slice Boolean
Calculate statistical properties for each slice.
Statistics per Frame Boolean
Calculate statistical properties for each frame.
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.
