关于matlab图像增强的源代码，可以用在实际生活背景中，例如雾天模糊图像增强等等(Image enhance)

为进一步细化频谱，提取有效的时频特征值，将信号进行局域波分解，本程序为主要程序(For further specified spectrum, extracting effective time-frequency characteristic value, signal will be decomposed with local wavelet.)

基于 MATLAB 的时域信号采样及频谱分析 基本要求：① 掌握数字信号处理的基本概念、基本理论和基本方法； ② 学会 MATLAB 的使用，掌握 MATLAB 的程序设计方法； ③ 学会用 MATLAB 对信号进行分析和处理； ④ 信号的各参数需由键盘输入，输入不同参数即可得不同的x(t) 和x(n)； ⑤ 撰写课程设计论文，用数字信号处理基本理论分析结果。 (MATLAB-based time-domain signal sampling and spectral analysis of the basic requirements: ① to grasp the basic concepts of digital signal processing, basic theory and basic methods ② learn the use of MATLAB, MATLAB programming method to master ③ learn to use MATLAB to analyze the signal and processing ④ signal parameters to be input from the keyboard, the input parameters can be different in different x (t) and x (n) ⑤ thesis writing course design, with the basic theory of digital signal processing analysis.)

S变换的matlab源码，并应用几个信号作为例子来说明怎么使用s变换以及s变换可以用来做些什么事情。s变换是时频分析领域中一个较新的内容，现在在信号处理，地震勘探，语音识别等领域都开始了对它的应用研究，是目前的一个热点。(S transform Matlab source, Applied Signal and several examples to illustrate how the use of Transform's's transformation can be used to do anything. Transform's time-frequency analysis is the area of a newer, now in signal processing, seismic exploration, Speech Recognition and other areas has started its applied research, is a hot spot.)
