应用傅立叶变换对图像处理，实现查看图像的功率谱，以及功率谱经过巴特沃斯高通、低通和高斯高通、低通滤波器后图像的功率谱，再把功率谱还原为图像的功能。(Fourier transform for image processing, see the image of the power spectrum, and the power spectrum after Butterworth high-pass, low-pass and high-pass Gaussian low-pass filter of the image after power spectrum, and then restore the power spectrum of the image.)

机器人的轨迹跟踪程序，修改参数可以重新建立自己想要的模型，可以看到末端轨迹的运动画面。(Robot trajectory tracking program, you can modify the parameters to re-establish the model you want, you can see the end of the trajectory of the moving picture.)

粗化细化程序很好用的，大家试市啊，(crude refining procedures of the good, we take the city ah,!)

说明：  一种新的图像清晰度评价函数,该函数对经典采用八方向模板Sobel边缘检测算子来检测梯度值(A new image definition evaluation function, which uses eight direction template Sobel edge detection operator to detect gradient value)

模式识别应用范围广泛，在机器学习，图像处理，运动目标检测与跟踪方面具有较大的应用价值。是本好书，值得推荐。(pattern recognition applied extensively in machine learning, image processing, moving target detection and tracking with greater value. Is a book worth recommending.)

用与水蒸气冷凝为水的程序，可以作为源项加入质量方程和能量方程(condensation UDF)

图像分解重构,用matlab实现图像压缩( image reconstruction Decomposition )

一个人写的sift代码，matlab实现，比起原作者的效果差些，但是也不错。（原作者没有公开源码）()
