I did not find anything mentioned in any of the release notes up to now stating that the old version of the Gaussian blur was wrong to some degree, so this leaves me very confused. Does anyone have any insights? Imho, a software update should not change the quality of standard algorithms...
Python numpy.random.normal() MethodThe numpy.random.normal() draw random samples from a normal (Gaussian) distribution. It takes some parameters like loc, scale, and size. Loc is the center of the distribution. Scale is the standard deviation of the distribution and size is the output shape...
