用matlab画出齿轮啮合面的三维模型，用于研究齿轮的啮合特性(Matlab to draw three dimensional models of gear meshing, used to study the gear meshing characteristics )

故障时频域特征提取，前六阶CEEMDAN+初始信号时频域特征(Fault time-frequency domain feature extraction, first six-order CEEMDAN + initial signal time-frequency domain feature)

in this program the horizon line detection is found out by using canny edge detector and hough transform.

this code gives various types of filter designs like chebbyshev and butterworth filters

里面含有相应的插值函数与相应的拟合函数，都用matlab程序实现了，而且都没有错误。(Which contains the corresponding interpolation function and the corresponding fitting function using the Matlab program, but there are no errors.)

Download the file town .jpg, which is a 1024×768, 256-grayscale image taken on a bright sunny day. The image was taken in the shadow of a building. As the result, the sunlight areas are glaring white and the shadow areas are dark and low contrast. Using the image enhancement techniques covered in class, increase the contrast and the brightness of the dark areas, and reduce the brightness of the sunny areas

Matlab关于傅里叶变换的pdf资料 有用(Matlab program on the Fourier transform)
