Application Of Mesh-Less Algorithms In Image Processing

Mesh-less method is a discrete governing equation which does not need to generate grids in numerical calculation and constructs interpolation functions according to some arbitrarily distributed coordinate points. This method can easily simulate flow fields of various complex shapes. In this paper, mesh-less method is applied to phase unwrapping in image processing of InSAR. This method can forbid error accumulate to the whole image in the sense of least squares. The precision of this method are can showed by real data.
