Fast three-dimensional phase-unwrapping algorithm based on sorting by reliability following a non-continuous path

In this paper, we propose a novel three-dimensional phase unwrapping algorithm that extends the “two-dimensional phase unwrapping algorithm based on sorting by reliability following a non-continuous path” into three dimensions. The proposed algorithm depends on a quality map to unwrap the more reliable voxels first and the less reliable ones last. It follows a non-continuous path to perform the unwrapping process. Computer simulation has demonstrated that the proposed algorithm is more suitable than its two dimensional counterpart when used to unwrap volumetric data.
