很好用的CT图像重建 ART算法matlab开发程序

基于图像梯度的图像识别,英文论文，一种通过图像梯度算法识别图像的方法，提出相对梯度在图像识别的应用(Gradient image based on image recognition, the English paper, an algorithm for identification of images through the image gradient method, proposed by the relative gradient of the application in image recognition)

粒子滤波算法比较,不同的建议分布下，粒子滤波的性能差异，包括精度与时间(the comparision)

this the code for spline fit

菲涅耳积分卷积方法的各种编程方法(Fresnel integral convolution method)

I have uploaded a code for DCT watermarking..I have embed a basic matrix into original image and calculated the difference.

【代码用法】Matlab工作区直接装载程序 【代码原名】Radio-Noise Removal 【代码功能】This data file can be loaded in matlab workspace.With pcolor(data);shading interp one can get the same plotted as a dynamic spectrum which looks like the uploaded picture that displays a solar radio burst enclosed within the box. The need is to plot the data such that only the burst is displayed in red color while the non burst region should be in violet as background.The fixed frequency interferences need to be subtracted.The x-axis is time and y-axis is the frequency.radio-data-noise-removal

改代码使用CCE方法来实现数据挖掘中多示例学习的过程。(CCE implements the algorithm described in [1], where Gaussian kernel LibSVM [2] is used as the base learner for transformed feature vectors.)

这段代码读取图像。然后计算 fft 的图像。然后首先删除振幅信息的 fft 计算 ifft 和第二删除 fft 相位信息计算 ifft。这段代码很有用可视化振幅和相位的快速傅里叶变换的图像内容。

this is a algorithm Fast PCA, it is very suitable for beginer who want to understand PCA, it is demo step by step
