matlab的fft函数使用注意事项，以及傅里叶变换的特征和理解。-Note the use of matlab' s fft function, as well as the Fourier transform of the characteristic and understanding.

采用各向异性方法 填补一个缺损的轮廓，从而可以得到一个光滑完整的轮廓。- Completed contours correspond to ridges of an extension (ext) of the characteristic function of the uncompleted curve. Anisotropic extension is performed on the characteristic function fbound of an image set

网站里没找到matlab版积分图hog特征函数，自己编了一个，应用于图像识别，直接调用-The site, did not find the matlab version of the integral image hog characteristic function, made up a used in image recognition, and direct calls

利用matlab编写函数实现RGB到XYZ空间的转换并利用这个函数对给定的图像进行处理，仿真手机屏上显示标准图片。在图像处理过程中考虑Gamma特性。-Matlab write the function RGB to XYZ space conversion and use of this function on a given image processing, simulation on the cell phone screen displays the standard picture.

通过对各种窗函数的matlab仿真，比较各种窗函数的频谱特性，并且将不同的窗函数加权到脉压信号上，观察特性的优劣-Based on all kinds of window function of matlab simulation, compare all kinds of window function, the characteristic of the frequency spectrum of and different window function weighting to the
