In this paper, we propose a robust surface reconstruction algorithm from the gradient field by minimizing the absolute error between the input and estimated gradient field from the reconstructed surface. The resulting L1 norm based cost function can then be efficiently solved via linear programming. Compared to conventional L2 estimation algorithms, the proposed approach is more robust to noise corruption and the influence of outliers, while still maintaining low computational cost and global… CONTINUE READING
