|Abstract: ||A new median-based filter, progressive switching median (PSM) filter, is proposed to restore images corrupted by salt-pepper
impulse noise. The algorithm is developed by the following two main points: 1) switching scheme—an impulse detection algorithm is used before filtering, thus only a proportion of all the pixels will be filtered and 2) progressive methods—both the impulse detection and the noise
filtering procedures are progressively applied through several iterations.
Simulation results demonstrate that the proposed algorithm is better than
traditional median-based filters and is particularly effective for the cases
where the images are very highly corrupted.|
