When low light level(LLL)image is processed by average filter, indistinctness may be caused seriousiy.In this paper, further studies and experiments are carriedout.

The experimental results show that snow noise filter can suppress theLLL image noise effectively; And as,for the protection to the image edge, the property ofsnow noise filter is better than that of average filler.

The fuzzy impulse noise detector using median value and neighbourhood information detects impulse noise. The impulse noise canceller uses minimum -maximum estimate method. The fuzzy filter is good at preserving fine details and suppressing impulse noise at the same time than other impulse noise...
