- Abstract
- Recently, as devices and communication technologies capable of acquiring digital images such as smart phones and digital cameras are developed, demand for digital images is increasing. However, the noise is generated in the process of acquiring, transmitting, and storing digital images. Therefore, in this paper, we propose an algorithm using an enhanced median filter and a Bitonic filter to reduce high-density impulse noise and preserve the edge region. Experimental results demonstrate that the proposed algorithm outperforms the conventional filtering techniques for high-density impulse noise.
