图像处理

CRF（条件随机场）的程序包，用于图像分析（恢复，分割），对图像进行建模(CRF (with the conditions of the airport) package for image analysis (restoration, segmentation), the image modeling)

说明：  图像分割代码，c++实现(Image segmentation code, c++ Achieve)

此文件一共包含3个m文件。第一个文件的功能是绘制一个二值图像，并显示其傅立叶幅度谱。文件2功能是设计频域理想低通滤波器，并加以验证：读入一个二值图像(cameraman.tif)加噪声后在频域进行低通滤波观察滤波后的图像效果。文件3的功能是对图像eight.tif加入椒盐噪声后，实现Butterworth低通滤波.(This file contains 3 m documents. Functions of first file is to draw a binary image, and displays its Fourier amplitude spectrum. Document 2 is designed to function a frequency domain ideal low-pass filter , and verified it: reading a binary image (cameraman.tif) plus noise on it and smoothing it in the frequency domain using low-pass filtering.The filtered effect will be observed by displaying image.Document 3 is designed to read a binary image(eight.tif) and add salt and pepper noise on it, realized frequence domain Butterworth low-pass filter.)

说明：  用来做小波分析，开源程序，可画出小波功率谱，小波全谱，程序中有参考文件的网址，非常方便·新手使用(Used to do wavelet analysis, open source program, can draw the wavelet power spectrum, wavelet full spectrum, the program has a reference file of the website, very convenient for beginners to use)

利用积分图的方式提取图像hog特征，用于人脸、行人检测。(Using the integral plot to extract the image hog feature, for human face, pedestrian detection.)

outguess 隐写源码，用于对于图像上附加秘密信息 (outguess steganography source code for additional confidential information for the image)

能够用 matlab确定模最大值，利用小波变换去噪，对地震信号进行处理(The maximum modulus can be determined by MATLAB, and the seismic signal is processed by wavelet transform denoising.)

说明：  使用贝叶斯算法进行图像分割，迭代法寻找最佳阈值(Bayesian algorithm is used for image segmentation, and iterative method is used to find the best threshold)

利用2张不同角度的图像，重建出三维图像 two view 3D reconstruction(Two different angles of the image, and reconstruct the three-dimensional image two view 3D reconstruction)

使用MATLAB生成二维voronoi图的代码，可以用作后续二维voronoi的多晶模型建立(The code of two-dimensional Voronoi diagram generated by MATLAB can be used to build the polycrystalline model of two-dimensional voronoi.)
