Is there a filter to normalise the input data?

[hxhxhx33 (Xu Han)]

I am rendering a 3D medical image, and want to normalize the input data to have a zero mean and unit variance, i.e. to subtract from each voxel the mean and then divide it by the std. I have googled but failed to find a solution. May I ask if there is a existing filter, or how I can achieve this? Thanks.

Hi,

The Python Calculator filter may be used to standardize values for image data.

The following is an example of applying it to a Wavelet source. Here, the following is written in Expression:

(RTData-mean(RTData))/std(RTData)
