In this paper, the part of apis based on minutia features includes mainly computing orientation, filtering, binarization, thinning, feature extraction, postprocessing and minutia matching ; the part of apis based on statistical features is composed of reference point location, extracting feature, classification and matching. some new approaches are brought forward : 1 ) in the preprocessing, a new binarization method of fingerprint images based on the orientation and the dynamic threshold is proposed, which has the excellent capability of noise resistance. this method makes fully use of the orientation and the characteristics of grayscale change, gets the binarized images from the primitive fingerprint images directly, instead of the series of processing such as smoothing, enhancement and binarization
本論文對這兩種系統做了深入地研究，從基於細節點特徵的系統中求取指紋方向圖? ?濾波? ?二值化? ?細化? ?特徵提取? ?后處理，到基於統計性特徵的系統中選取指紋圖像參考點? ?提取統計性特徵? ?分類? ?匹配等環節，都一一進行了討論，並提出了一些新方法： 1 ）在基於細節點特徵系統的預處理部分，本論文提出一種新的基於方向圖具有動態閾值的指紋圖像二值化方法，這種演算法能夠在保持特徵點不丟失的基礎上一次性完成一般指紋圖像處理中的無效塊分割、增強、濾波、二值化的過程。
