MOSCHETTI, E. et al. On the use of Lee's protocol for speckle-reduncing techniques. Lat. Am. appl. res. [online]. 2006, vol.36, n.2, pp.115-121. ISSN 0327-0793.

This paper presents two new MAP (Maximum a Posteriori) filters for speckle noise reduction and a Monte Carlo procedure for the assessment of their performance. In order to quantitatively evaluate the results obtained using these new filters, with respect to classical ones, a Monte Carlo extension of Lee's protocol is proposed. This extension of the protocol shows that its original version leads to inconsistencies that hamper its use as a general procedure for filter assessment. Some solutions for these inconsistencies are proposed, and a consistent comparison of speckle-reducing filters is provided.
