图像增强

说明：  基于RSA的图像加密过程，进过扩散等进行加密处理。(Based on the blockchain image encryption process, through diffusion and other encryption processing.)

icp算法C++实例，用于点集的配准，实现两片点云数据的拼接(icp algorithm C++ instance, used for the registration point set to achieve splice two pieces of point cloud data)

说明：  使用halcon操作XML文件的例子，可以直接使用。仅供学习交流(Read And Write XML By Halcon)

说明：  通过偏振进行图像处理和图像复原，利用大气光和物体反射光的光学模型进行复原(Image processing and restoration are carried out by polarization, and restoration is carried out by optical model of atmospheric light and object reflected light)

DNA比对中FASTA算法的简单实现，通过建立查找表、位移表和位移向量表来得出两条序列的最大匹配位移。(DNA matching the FASTA algorithm is simple to achieve, through the establishment of a lookup table, displacement and the displacement vector table to derive maximum matching two sequences displacement.)

说明：  以稀疏基有离散余弦变换基（DCT）和快速傅立叶变换基（FFT）做为稀疏基，高斯随机矩阵、部分哈达玛矩阵为测量矩阵，L1范数、正交匹配追踪算法（OMP）为重建算法进行压缩感知算法实现。 以f = cos(2*pi/256*t) + sin(2*pi/128*t)做为原信号，取原信号f的20%做为输入进行压缩感知重建。(The sparse basis includes discrete cosine transform (DCT) and fast Fourier transform (FFT) as sparse basis, Gaussian random matrix and partial Hadamard matrix as measurement matrix, L1 norm and orthogonal matching pursuit algorithm (OMP) as reconstruction algorithm. In this paper, the reconstructed signal is reconstructed by using the original sensing signal (sinf * t) as the original input signal (i.e. sinf * t * 2) + 2 * s * t * as the input signal.)

本代码是做指纹识别是代码，平台是MATLAB，能够完成指纹识别、处理、匹配整个过程。(This code is to do fingerprint identification code, the platform is MATLAB, able to complete the fingerprint identification, processing, matching the whole process.)

说明：  平面拟合，RANSAC拟合方法，关于平面重构，画示意图，计算法向量(Plane Fitting and RANSAC Fitting Method)

计算Zernike矩，对图像进行了平移，尺度归一化(Computing Zernike moments, the image of the translation, scaling normalization)
