hallo, I need use the Gaussian filter to smooth the images according to an Algorithm from a paper. it says: "smoothing the image with an 11-pixel Gaussian filter with a standard deviation of 11 pixels". it means I think, the sigma should be dynamically changed with Pixels covered by the filter. can someone help me how to achieve it? thank you in advance. Qu Z.

That interpretation sounds really different from what is usually meant by smoothing. How I read this, is that they had a normal Gaussian filter with an SD of 11 pixels, but that is only 11 by 11 pixels large, which seems a bit small given the the SD.
