Parameters | Functional description |
---|---|
ρ | To initialize the level set function. ρ > 0 is a constant. |
σ | Scale parameter in Gaussian kernel (GCV: σ = 1; LBF: σ = 3; our model: σ = 5). |
λ 1 | Inner weight of contour C (LBF: λ 1 = 1). |
λ 2 | Outer weight of contour C (LBF: λ 2 = 1). |
ϵ | The parameter of H 3 and δ 3 (LBF: ϵ = 1; our model: ϵ = 0.3). |
∆t | Time step (GCV: ∆t = 1; LBF: ∆t = 0.1; our model: ∆t = 1). |
β | The weight of ω (our model: β = 1). |
π | π = 3.14 is a constant. |
α | Balloon force (GCV and our model: α determined according to images). |
