    本文在脊線二值化過程中充分考慮了這兩個特性，並且利用指紋圖像中點梯度的方向信息，提出了用相位編組法確定塊方向，然後基於塊方向進行方向濾波，收到了較好的效果。
  2. Making use of the ridge tracing results, the algorithm can obtain some attributes of the feature points. combining the attributes and the local structural information, it can identify and eliminate the false feature structures, so as to eliminate the false features.
