Estimation of Salt-Pepper Noise in Images Using Joint Entropy

摘要: We proposed an approach for estimating the density of salt-pepper noise in images using joint entropy value. The between noisy image and original or other typical was introduced this paper to depict inter-correlation. revealed how value changes along with density, we indicates that relation is robust individual traits. Finally represented such quantitative form took advantage make estimation density. Simulation results showed outperforms those existing methods.
