frft
矩形信号的frft(分数傅里叶变换wigner_ville_1.m 单分量信号去噪
wigner_ville_2.m 双分量平行信号去噪
wigner_ville_3.m 3分量信号频率检测)分数傅里叶变换是经典傅里叶变换的另一种改进方式。它的主要特点是提供研究对象从时间域到频率域全过程的综合描述,随着阶数从0连续增长到1,分数傅里叶变换展示出研究对象从纯时间域逐步变化到纯频率域的所有变化特征。因此,分数傅里叶变换提供了远比傅里叶变换多得多的可供选择的数据处理和分析方法。(The rectangular signal FRFT (Fractional Fourier Transform) Score Fourier transform is another modification of the classic Fourier transform. Its main feature is a comprehensive description of the study from the time domain to the frequency domain, with the order of continuous growth from 0 to 1, the fractional Fourier transform demonstrate the object of study from a purely time-domain gradually change to a pure frequency domain variation. Thus, the fractional Fourier transform provides data processing and analysis methods than Fourier transform much more to choose from.)

高斯平滑滤波实例,高斯滤波实质上是一种信号的滤波器,其用途是信号的平滑处理,我们知道数字图像用于后期应用,其噪声是最大的问题,,由于误差会累计传递等原因,很多图像处理教材会在很早的时候介绍Gauss滤波器,用于得到信噪比SNR较高的图像(反应真实信号)。
(Instance of the Gaussian smoothing filter, Gaussian filter is essentially a signal filter, its purpose is to smooth processing of the signal, we know that the digital image for the late application, the noise is the biggest problem, the error accumulated transfer reason, a lot of image processing textbooks will be introduced at an early Gauss filter for higher SNR of the image (real response signal).)

精通Matlab数字图像处理与识别
数字图像处理(Digital Image Processing)是通过计算机对图像进行去除噪声、增强、复原、分割、提取特征等处理的方法和技术。 [1] 数字图像处理的产生和迅速发展主要受三个因素的影响:一是计算机的发展;二是数学的发展(特别是离散数学理论的创立和完善);三是广泛的农牧业、林业、环境、军事、工业和医学等方面的应用需求的增长(Digital Image Processing (DIP) is a method and technology of removing noise, enhancing, restoring, segmenting and extracting features from images by computer. [1] The emergence and rapid development of digital image processing are mainly influenced by three factors: first, the development of computer; second, the development of mathematics (especially the establishment and improvement of discrete mathematics theory); third, the growth of the demand for extensive applications in agriculture, animal husbandry, forestry, environment, military, industry and medicine.)
