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)

基于梯度相似度的图像质量评价方法，发表在2012年TIP国际期刊上(A. Liu, W. Lin, M. Narwaria, “Image Quality Assessment Based on Gradient Similarity,” IEEE Transactions on Image Processing, vol. 21(4), pp. 1500-1512, 2012.)

进行图像区域合并操作,能够较为有效，较好的进行图像合并(combine the image，very effcient)

文简要介绍了指纹识别的基本步骤，分别是指纹图像预处理、指纹特征提取、指纹匹配(This paper briefly introduces the basic steps of fingerprint recognition, which are fingerprint image preprocessing, fingerprint feature extraction and fingerprint matching)

在数字图像处理中.应用MATLAB对图像进行区域处理(In digital image processing. Application of MATLAB to deal with images of regional)

说明：  基于傅立叶梅林变换的图像配准算法可以控制旋转缩放参数实现配准(Fourier Mellin transform based image registration algorithm can control the rotation scaling parameters to achieve registration)

说明：  对图像进行插值，以提高分辨率，计算效率较高(The image is interpolated to improve the resolution)

本程序实现灰度图像各向异性扩散(Anisotropic Diffusion)滤波算法，可以用于平滑信号，保留边缘，增强边缘对比度。与普通高斯Gaussian算法相比，它不会平滑边缘的图像。(The program implements grayscale image using anisotropic diffusion filtering algorithm.It can be used to smooth the signal, keep the edge, enhance the edge of the contrast. Compared with ordinary Gaussian algorithm, it does not smooth the image edges.)

基于MATLAB的图像配准算法（高斯金字塔与其他几个算法）(MATLAB-based image registration algorithm (Gaussian pyramid with several other algorithms))

极坐标图像转直角坐标图像，相当于球面的展开效果，最好是正方形图像，但是长方形也可以。(POLARTOIM converts polar image to rectangular image)
