title = "Efficient algorithms for approximating a multi-dimensional voxel terrain by a unimodal terrain",

abstract = "We consider the problem of approximating a function on a d-dimensional voxel grid by a unimodal function to minimize the L2 approximation error with respect to a given measure distribution on the grid. The output unimodal function gives a layered structure on the voxel grid, and we give efficient algorithms for computing the optimal approximation under a reasonable assumption on the shape of each horizontal layer. Our main technique is a dominating cut algorithm for a graph.",
