GVF model derives from generalized force balance equations, a vector diffusion equation is employed to diffuse the gradient of an edge map in regions distant from the boundary, yielding a general type of force field which can be decomposed into an irrotational component and a solenoidal component.
梯度矢量流(GVF)模型是从广义力平衡方程出发,利用能量最小公式,应用扩散方程扩散了边界区域的边缘映射梯度,产生了一种广义矢量场,包含无旋分量和无散分量。
We represent the unknown currents in terms of its solenoidal and irrotational components and use Loop/ Tree basis function as the expansion function, respectively.
先将未知的电流密度分成有旋和无旋两部分,并分别采用Loop基函数和Tree基函数进行展开,展开后的未知数的个数与传统的矩量法相等。
