Abstract A new unwrapping algorithm-Nearest Point Linking (NPL) algorithm is presented based on the Goldstein algorithm. It decreases the residue number by smoothing the couple residues in nearest distance. Then, the Goldstein algorithm is applied to link the other residues. As a result, a good solution is achieved. The experiment shows the validation of the algorithm in high-density residue condition.
