KURTOSIS Function (PV-WAVE Extreme Advantage)
Computes the kurtosis of an array.
Usage
result = KURTOSIS(array)
Input Parameters
array—An array of any data type except string.
Returned Value
result—A double array containing the kurtosis of array.
Keywords
None.
Discussion
Kurtosis is a useful measure for statistical texture analysis. The KURTOSIS function computes the kurtosis of array(k, l) as:
where mean = AVG(array) and std = STDEV(array).
Example
; Read an image.
image = IMAGE_READ(!IP_Data + 'noise_test.tif')
; Compute the kurtosis of the image.
kurt = KURTOSIS(image('pixels'))PRINT, 'Kurtosis = ', kurt
