在梯度基础上使用加权平均提取指纹方向场然后使用高斯滤波进行平滑处理(Extraction of fingerprint orientation field using weighted average based on gradient)

图像质量评价代码： 灰度平均梯度 边缘能量 方差 点锐度(image quality evalution method)

对特征值进行非极大值抑制的角点检测，并且选用了合适的阈值加强检测效果(corner detection by non-maxima suppression of Eigenvalues and selected the appropriate threshold to enhance detection)

利用Retinex中心环绕算法进行阴影去除，飞常详细并含有程序对应的PPT(Centers around the use of Retinex algorithm to remove the shadow, flying often detailed and contain procedures for the corresponding PPT)

IDL编写的以时间为变量的散点图代码,值得新手学习(IDL prepared time-variable scatter plot code, novice worth learning)

用基于稀疏表示和KSVD字典学习去噪方法在对数域对SAR图像抑斑，本方法相对于一些经典的SAR图像抑斑方法，抑斑效果大大提高。(Based on the sparse representation and KSVD dictionary learning denoising method in the logarithmic domain，we despeckle SAR image, compared with some of the classic SAR image speckle suppression method, this method is much more effective.)

说明：  super resolution可实现 很多算法(a lot of super resolution algorithms can be realized)

图像配准和拼接，肯定可以使用。。。harris+ransac(Image registration and stitching, they can definitely use. . .)

数字图像处理有关于图像去雾的新型算法与实现(There are new digital image processing algorithms on the image to go to the fog and Implementation)

一个比较不错的水平集改进算法，内附说明文档。(A relatively good level set to improve the algorithm, containing documentation.)
