本程序是基2的时间抽取FFT变换，可以将信号从时域转换到频域。(This procedure is the base 2 time extraction FFT transform, can transform the signal from time domain to frequency domain.)

说明：  三次B样条曲线，计算机图形学实验中的一个小程序，很有意思哦(Three B-spline curves, Computer Graphics in a small experimental procedure, very interesting oh)

说明：  Simple Thumbnail Viewer PRINT

relief 特征选择算法，用来约简数据属性。图像处理等(Relief feature selection algorithm is used to reduce data attributes. Image processing, etc.)

说明：  用matlab实现color moments算法，先把rgb图像转换到HSV空间，然后计算每个分量的一二三阶矩，最后组成9维向量进行比较。(Using color moments algorithm matlab realize, first convert rgb images to HSV space, and then calculated for each component of the 123-order moments, the final composition of 9-dimensional vector for comparison.)

说明：  基于DSP和FPGA芯片的实时图像处理系统。该系统不同于传统基于PC机模式的图像处理系统，发挥了DSP和FPGA两者的优势，能更好地提高图像处理系统实时性能，同时也最 大可能地降低成本。(Real time image processing system based on DSP and FPGA. This system is different from the traditional image processing system based on PC mode. It can improve the real-time performance of the image processing system better by using the advantages of DSP and FPGAIt is possible to reduce costs.)

说明：  IDL读取txt，txt第一列是纬度，第二列是经度，第三列是DN值， 坐标转行列号 ，并以图像的形式输出(IDL reads TXT. The first column of TXT is latitude, the second column is longitude, and the third column is DN value. The coordinate turns the line and column number and outputs it in the form of image)

　找出图象的最佳阈值，并显示它的二值图．(find the best image threshold, and it shows the value of Figure 2.)

影像融合评价程序，计算标准偏差，平均梯度，相关系数，光谱扭曲度等融合指标。(Image fusion evaluation, calculation of standard deviation, average gradient, correlation coefficient, spectral distortions, such as integration targets.)

改进后的pca用于故障检测与诊断，应用于TE的化工过程，仿真结果比传统的pca方法效果更好(Pca for improved fault detection and diagnosis of chemical process applied to TE, the simulation results than the traditional method pca better)
