Compression and decompression using huffman code

image sharpening using matlab

OFDM_rece_matlab 的程序(OFDM_rece_matlab procedures)

FSK modulation scheme with offset

这个matlab程序实现的是一个噪声生成器，它可以生成高斯、椒盐、加性及乘性噪声，并把这些噪声添加到一幅图像上。(Gaussian Pepper Noise Generator)

傅里叶变换后频谱图 B：陷波函数作用后的频谱图 C：经逆变换的滤波后图像，效果不是很理想 Ifft2：为验证自己的快速傅里叶变换程序的正确性，用matlab自带逆变换程序将频谱逆变换后图形，与原图相符，说明快速傅里叶变换程序正确。(This is a FFT )

this the matlab codes for detection of surveillance system and its working.and also there is motion detection codes in it

说明：  lorenz系统分岔轨迹绘制，包含吸引子图，X,Y,Z相时间序列(lorenz draw bifurcation path, including the attractor graph, X, Y, Z-phase time-series)

用MATLAB函数实现图像DCT域信息隐藏和提取，绘制控制阈值、JPEG压缩域与隐藏鲁棒性的关系图，对实验效果进行分析。(DCT domain information hidden field extraction)

ITU-T G.723.1 Speech Coder: Matlab implementation This package implements the speech coder and decoder. Full documentation is in the PDF file included with the package. The test folder has test programs for the coder and decoder (for Windows).
