主要介绍了基于（单、多）高斯统计模型的背景获取法(Mainly based on the (single, multi-) Gaussian statistical model to obtain the background of law)

Midpoint Filtering for Noise Reduction

Estimation of direction in degree for doa study

通过比较循环相加法和重叠保留法的性能，使用重叠想加法来进行音频信号的去噪(Overlap-add and overlap-save method is a method of two methods used to seek a finite sequence of linear convolution. Through performance comparison of the two methods, select the overlap-add method de-noising experiments )

1.掌握图像滤波的基本定义及目的； 2.理解空域滤波的基本原理及方法； 3.掌握进行图像的空域滤波的方法。 (1. Image filtering grasp the basic definition and purpose; 2. Understanding of spatial filter the basic principles and methods; 3. master images of the spatial filter method.)

对于输入的bmp图像进行rgb三个分量的提取 利用直方图显示(rgbhist display)

字母图像识别算法，O, E, A, U 四个字母进行识别，该算法加入一定噪声之后依然有效。(The basic goal of the program is to perform letter recognition of vowels O, E, A, U in paragraphs provided in form of black-and-white images. Using the training paragraph image, we are allowed to train our program to distinguish among letters. Some difficulties that need to be resolved are noise, joined letters, scaled or tilted letters, and distinguishing between letters that are similar to each other. )
