| After creating the 2D kernel weights, the smoothing is applied in iterations. During each iteration, each vertices value is replaced by a weighted sum of the value itself and an equally inter-neighbor weighted sum of the first-degree neighbors: | After creating the 2D kernel weights, the smoothing is applied in iterations.

| In other words, the central kernel weight remains with the old value and the remainder to 1 is split across the next neighbors according to the kernel weight given by their distance to the vertex. This approach takes both the neighborhood and the distance of vertices into account. | In other words, the central kernel weight remains with the old value and the remainder to 1 is split across the next neighbors according to the kernel weight given by their distance to the vertex.
