laplacian边缘检 图象进行降噪处理 高斯滤波处理-laplacian edge detection image processing Gaussian filter processing for noise reduction

单帧播放，打开，关闭，高斯处理、模糊、降噪视频。-Single-frame playback, open, close, Gaussian processing, blur, noise reduction video.

本算法在实验室环境下录制语音，并加入matlab仿真软件产生的高斯噪声，成功实现了谱减法语音降噪-Record the voice of the algorithm in a laboratory environment, and added matlab simulation software generate Gaussian noise, the successful implementation of spectral subtraction speech noise reduction

分别编写BPSK与QPSK调制解调系统的Matlab仿真程序，要求：发送滤波器与接收滤波器均为根升余弦滚降滤波器；信道噪声为加性高斯白噪声 绘制BPSK与QPSK调制下的误码率与信噪比曲线图，并与理论曲线比较对比-They were written BPSK and QPSK modulation and demodulation system Matlab simulation program requirements: a transmission filter and a recept

时域高斯图像滤波,用于图像降噪。速度快，简洁明了(time domain gaussian filter)
