    Nowe podejście do usuwania szumu na drodze filtracji medianowej
    (Wydawnictwa AGH, 2007) Fabijańska, Anna; Strzecha, Krzysztof; Sankowski, Dominik
    In the paper, algorithm for removal of noise was presented. Proposed algorithm is based on median filter and it works in two stages: in the first stage, there is built map of point, which brightness level should be changed in the second stage. Deep analysis of the algorithm was provided.

    Two-pass median filter for impulse noise removal
    (Wydawnictwa AGH, 2009) Fabijańska, Anna
    In this paper the new approach to impulse noise removal is introduced. Described algorithm involves modification of median filtration mechanism. However, in opposition to traditional approach only pixels corrupted by noise are filtered. Results of applying introduced method to exemplary images are presented and compared with results achieved with traditional approaches. Moreover, the performance of the method is analyzed. Factors influencing efficiency of noise removal using proposed algorithm are deliberated.
