A method for reduction of noise in a digital images. A pixel is added to a region (R). Thereafter is the surrounding symmetrically located pixels, touching the region, grouped in pairs and if a condition is fulfilled the pixels are added into the region, otherwise not. When no more pixels fulfils the condition, the region is averaged and the average will substitute the noised pixel. Also a method for noise reduction where an estimate for the noise fluctuation is formed from a second image is described. The estimate will form a correlated estimate for a first image and therefrom a noise reduced first image will be reconstructed. |
