MENDIOLA-SANTIBANEZ, Jorge Domingo et al. Morphological Filtering Algorithm for Restoring Images Contaminated by Impulse Noise. Comp. y Sist. [online]. 2015, vol.19, n.2, pp.243-254. ISSN 1405-5546.

In this paper a methodology to restore gray scale images with pixels polluted by random impulsive noise is presented. Noise is discovered using a criterion based on the white top-hat by reconstruction. Pixels detected as corrupted are restored using an iterative morphological algorithm built with extensive and antiextensive morphological transformations. The proposal is compared with the rank ordered mean filter (ROM) and other morphological transformations reported in the current literature.

Keywords : Noise detection; morphological pixel restoration; transformations by reconstruction.
