Hi,
Please use the mailing list for your RTK questions, it's of interest to everyone. From the command line, there is no option to filter the images with a Gaussian. If you use Python wrapping, I recommend SimpleITK which should have such filters. If you program a C++ application, you can use one of the Gaussian filters of ITK, there are many.
For noise, you have rtk::AdditiveGaussianNoiseImageFilter in RTK.
Let us know if you need more information

Hi Dr. Rit,



I am a researcher at Cleveland Clinic, Ohio, USA. I am trying to use your code to process some CT images. I am wondering if you have some instructions about how to add Gaussian Blur and Gaussian Noise on to my images. Thanks!




Best


Richard
