WebAnswer (1 of 2): If they sum up to greater than 1, then your image will get brighter after blurring. If they sum up to less than 1, then your image will get darker afterwards. WebBinomial distributions can be approximated by Gaussian distributions, so it should be true that Gaussian distributions can also be approximated by binomial distributions. You can obtain binomial distributions with p = 1 / 2 by convolving the length 2 kernel: 1 2 [ 1 1] by the length 2 kernel multiple times. WebI am trying to derive the normalizing constant for the multivariate Gaussian. The book I'm following suggests diagonalizing the covariance matrix and then using a change of variables.
