该文利用专门的指纹采集设备获取指纹基本图像，基于MATLAB对指纹图像进行预处理，包括图像增强、图像二值化、分割和归一化。对指纹特征提取指纹类型、坐标和方向参数后，利用BP神经网络进行训练识别。识别实验效果明显，识别率高。
該文利用專門的指紋採集設備穫取指紋基本圖像，基于MATLAB對指紋圖像進行預處理，包括圖像增彊、圖像二值化、分割和歸一化。對指紋特徵提取指紋類型、坐標和方嚮參數後，利用BP神經網絡進行訓練識彆。識彆實驗效果明顯，識彆率高。

In this paper, special fingerprint acquisition device is used to obtain the basic fingerprints, fingerprint preprocessing base on MATLAB , including fingerprint enhancement, binary the fingerprint, segment as well as normalization. Extracting fin-gerprint types, coordinates and direction parameters, then the BP nerve network is used to train and identify fingerprint. The re-sult of recognition is obvious, it has high recognition rate.
