Research output: Contribution to journalArticlepeer-review


In this letter, we propose an improved bilateral filter of high capability of removing impulse noise with maintaining smoothness of signal and edge preservation. Our improved bilateral filter incorporates an idea of the iris filter into the bilateral filter. We show the effectiveness of our improved bilateral filter through experiments using some example images. The experiments show that our improved bilateral filter can remove impulse noise and maintains image smoothness while preserving edges.
