A homomorphic system to reduce speckle in videos

Abstract

In this paper, we propose an unbiased homomorphic system to reduce speckle in videos. The speckle is modeled as a multiplicative noise having a lognormal distribution. In the proposed homomorphic system, first, the natural logarithm function is applied on the corrupted signal to transform the multiplicative nature of the noise into an additive one. Then, a… (More)
