Compute the kurtosis of the input image. Kurtosis is a measure of how outlier-prone a distribution is.

 

function call:

[num1]=vsg('KurtosisCalc',in_img1);

 

Arguments:

in_img1 input image, 3 channel RGB, 1 channel greyscale or binary image, or DICOM image.

 

Description:

num1 – a double representing the greyscale intensity kurtosis for the image.

 

Example:

img = openimage('lake.jpg');

[num1]=vsg('KurtosisCalc',img)

 

num1 = -0.1724

 

Notes:

1. For DICOM images, the function finds the kurtosis value across all slices.

2. For RGB images, the function finds the kurtosis value across all colour planes.
