Noise Variance Estimation Based on Knowledge of Noise Reduction Coefficient
Jakub Pęksiński, Mikolajczak Grzegorz · Advanced materials research · 2011
The paper presents interference estimation method involving search for “flat” area, on the basis of image analysis taking into account correlation coefficient and knowledge of variance reduction coefficient for noise in the filtered area. The proposed method was tested for an interference characterised by normal distribution, and then compared to the other ones.
