频域滤波器

说明：  编译的图形软件的一部分程序可以画出直线圆弧矩形(graphics software compiler part of the procedure can draw straight rectangular arc)

提取视频中的图片，每一帧的信息，把视频分为图片信息(get picture of video)

说明：  标准图像库，里面有国际上通用的标准图像，用于图像处理(Standard image library, which has a common international standard image)

说明：  使用中值，均值，小波，DCT，PCA五种方法实现对图像的去噪处理。(Five methods, median, mean, wavelet, DCT and PCA, are used to denoise the image.)

说明：  图片的加法运算减法运算乘法运算除法运算和四则运算(Four Operations of Addition, Subtraction, Multiplication and Multiplication of Pictures)

实现模糊聚类算法（FCM）与马尔科夫随机场空间约束（MRF）的图像分割、SAR图像变化检测(Fuzzy Cluster Method and Markov Random Field for Image Segmentation or SAR Change Detection)

JPEG2000自己编写的代码，与标准版有所不同，里面有详细注释，可以运行(Own code JPEG2000 Standard Edition is different, there are detailed notes, you can run)

说明：  中国7大地理分区shp文件，东北、华北、华东、华中、华南、西南、西北七大经济协作区(Shp files of seven geographical regions in China)

说明：  数字图像处理 小波处理 ，去噪音，比基于傅里叶变换的去噪方法好。 含噪信号经过预处理，然后利用小波变换把信号分解到各尺度中，在每一尺度下把属于噪声的小波系数去掉，保留并增强属于信号的小波系数，最后再经过小波逆变换恢复检测信号。(The noisy signal is pre-processed, then the signal is decomposed into different scales by wavelet transform. The wavelet coefficients belonging to noise are removed at each scale, and the wavelet coefficients belonging to the signal are retained and enhanced. Finally, the detected signal is restored by inverse wavelet transform. It is better than the denoising method based on Fourier transform.)

本人图像处理的期末课程作业，使用模式识别自动识别验证码。老师都给好评哦(I end image processing course work, the use of pattern recognition automatic identification code)
