利用Zernike方法对圆形标志点中心进行提取(The circular mark center is extracted by Zernike method.)

彩色图像的arnold图像置乱和logistic混沌序列的图像加密程序matlab源码(Color image of arnold image scrambling and logistic chaotic sequence of image encryption program Matlab source)

利用hough变换检测图像中的形状圆和直线，以及图像几何变换(detecting image circle or line using hough transformation and transformation)

此程序可以根据一幅图像的DEM读取一幅图像(This program can read an image of an image based on DEM)

基于傅里叶描述子对旋转、平移等运动的不敏感性，识别目标(recognize the objects with rotation, translation, etc based on fourier descriptor.)

改进的小波算法，主要对小波二次分解进行了改进(Improved wavelet algorithm, mainly secondary wavelet decomposition is improved)

引导滤波器，在引导图像的引导下对输入图像进行滤波，这种新型滤波器对边缘的保持很好，而且运行计算量和核的大小无关(Guide filters, under the guidance of the guide image filtering the input image, the edge of this new type of filter to keep well and run the calculation regardless of the size and nuclear)

harris角点检测，并且实现两幅图像特征点的匹配，最终完成图像的拼接(harris corner detection, and realize two image feature point matching, the final completion of image stitching)

显示不同类型的色表，并查找相应区域或位置的值。 基于idl编程 (Show the different types of color tables, and find the corresponding value of the region or location. Idl-based programming)

对整幅三维影像数据进行Butterworth高通滤波处理（10阶2次），先进行傅里叶变换，利用巴特沃斯高通滤波器数学模型进行变换，在傅里叶逆变换得到新数据(For the entire three-dimensional image data Butterworth high-pass filtering (10-order twice), the first Fourier transform, use Butterworth high-pass filter to transform the mathematical model, the inverse Fourier transform to obtain new data)
