"This depends a lot on your images, in particular on the pixel size. In general, the chosen $\\sigma$ should be large enough to blur out noise but small enough so the \"structures of interest\" do not get blurred too much. Usually, the best value for $\\sigma$ is simply found by trying out some different options and looking at the result. \n"
