COMPRESSION

说明：  基于PCA的人脸表情识别，可以辨别高兴，愤怒和厌恶三种表情。 (In this project, Eigenfaces are used to classify facial expression. It has been assumed that, facial expression can be classified into some discreet classes (like anger, happiness, disgust or sadness) whereas: 1. Absence of any expression is the "Neutral" expression 2. Intensity of a particular expression can be identified by the level of its "dissimilarity" from the Neutral expression)

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.)
