Combined homomorphic and local-statistics processing for restoration of images degraded by signal-dependent noise
Henri H. Arsenault, Martin Lévesque · Applied Optics · 1984
The generalized homomorphic transformation to make signal-dependent noise independent of the signal is combined with a local-statistics image restoration technique to process images degraded by signal-dependent noise. Experimental results are given for images degraded by film-grain noise and by multiplicative noise.
