(ii) MMEM: dpecifically designed for "salt and pepper" noise and high noise ratios .
(3) The best method when the noise is high (or very high) is the MMEM and for low and medium is MDBUTMF.
The results for high noise ratios were superior to those obtained for MDBUTMF and were close to those obtained using MMEM, which is specifically designed for high noise ratios.
Some reconstruction examples are shown in Figure 10 where MDBUTMF and MMEM are compared to SVMM2 and SVM-R (more results for different methods and different images can be found in http://agamenon.tsc.uah.es/Investigacion/gram/papers/Noise/).
For a high noise ratio (90%), the image was reconstructed by MMEM and SVMM2 but the recursive nature of SVM-R yielded poor results.
As an example, MMEM is really simple and a training is not needed to obtain good results for high noise ratios.
