| Abstract: | According to the robust of L_1 norm, this paper combines L_2 norm with L_1 norm and gives a solution of L_2/L_1 norm in two phases for deformation network. Comparing with least squares method by using two examples, the results are as follows: if there is a displacement of single point in the network, the estimate of least squares method is biased, but the solution of L_2/L_1 norm can reliably obtain the changed information and displacement of each point. |
