In example 2 that you give, your data is drawn from a multivariate gaussian with covariance R. You specify the bandwidth as h = 1, yet you pass the data in it's raw form. Do you not need to whiten the data first if you are going to specify the bandwidth as 1?


Hi, can you please tell me how to use this code to compute the information potential of an image.

I'll plan to upload lot of my matlab works inside (maybe more than 200 functions/toolboxes)

Excellent job! The code is nicely written and commented. FGT is very useful in many application and having its mex implementation in Matlab helps a lot. Do you have a code web page or something to cite (in case somebody use you code)?
