Figure 4From: Complementary tensor-driven image coherence diffusion for oriented structure enhancementDiffusion for wood texture. (a) Original wood image, (b) complementary diffusion by our approach σ = 0.01, ρ = 1.2, iteration time = 6, (c) coherence-enhancing method by Weickert σ = 0.01, ρ = 1.2 iteration time = 6, and (d) diffusion by P-M equation σ = 0.01, iteration time = 3.Back to article page
