fingerprint-feature-extraction-
本文设计了一套指纹图像预处理和指纹特征提取算法, 利用方向滤波的方法对原始图像进行增强,使用改进的细化算法进行细化, 最后基于脊线跟踪的方法, 用改进的算法更为简洁而有效地避免了各种伪特征。设计的算法经Matlab 实现, 实验效果良好。(Designed a fingerprint image and fingerprint feature extraction algorithm using directional filtering the original image enhancement, improved thinning algorithm refinement, the last ridge line tracking method, the improved algorithm is more simple and effective way to avoid the pseudo-characteristic. Design algorithm with Matlab, the experiment well.)

matlab实验程序
说明: (1)利用matlab函数进行噪声模拟,并用matlab自带函数进行图像滤波。
(2)利用给定图像自己编程实现使用均值滤波器、中值滤波器对不同强度的高斯噪声和椒盐噪声,进行滤波处理,并对结果进行评价分析,并解释结果。
(3)自己编程实现laplacian算子图像的处理,实现图像增强;编程实现sobel算子对图像边缘提取。将结果与matlab自带函数计算结果比较。
(4)利用模糊处理对图的灰度值进行改变实现灰度增强,并与直方图均衡结果比较((1) Matlab function is used to simulate noise, and Matlab function is used to filter image.
(2) Using the given image, we use the mean filter and median filter to filter the Gaussian noise and salt and pepper noise with different intensities, evaluate and analyze the results, and interpret the results.
(3) The image processing of Laplacian operator and image enhancement are realized by programming
Sobel operator is used to extract image edge. The results are compared with those of MATLAB.
(4) Fuzzy processing is used to change the gray value of the image to achieve gray enhancement and balance with histogram)
