• A NEW HYBRID FILTERING TECHNIQUE FOR REMOVAL OF IMPULSE NOISE FROM DIGITAL IMAGES

Abstract

Removing impulse noise from digital image is a very active research area in digital image processing. In recent years, technological development has significantly improved in analyzing digital images. This paper proposes a new hybrid filtering technique (HMMF) for the removal of impulse noise from digital images, by topological approach. The quality of the noise reduction in images is measured by the statistical quantity measures: Root Mean Square Error (RMSE) and Peak Signal-to-Noise Ratio (PSNR). The performance of this filter on images tainted with various noise levels of impulse noise is compared with some existing filtering techniques.
