Figure 2From: Complementary tensor-driven image coherence diffusion for oriented structure enhancementDiffusion for tree texture. (a) Original tree texture, (b) complementary diffusion by our approach σ = 0.1, ρ = 1.2, iteration time = 6, (c) coherence-enhancing method by Weickert σ = 0.1, ρ = 1.2 iteration time = 6, and (d) diffusion by P-M equation σ = 0.1, iteration time = 3.Back to article page
