Kurtosis function on image

I would like to calculate the Kurtosis of an image in matlab. Matlab has a function kurtosis I can use this function on a matrix. For example:

m = rand([4 5]);

Though when I use this grayscale image:

I = imread('0.tiff');

I get this error:

Error using - Integers can only be combined with integers of the same class, or scalar doubles.

Error in kurtosis (line 39) x0 = x - repmat(nanmean(x,dim), tile);

My question now is: What am I doing wrong, and how can I calculate the kurtosis of an image.


kurtosis needs I to be double. This works:


or this
