lzw图像压缩

说明：  通过高斯函数导数检测图像边缘，实质是方向可调小波变换检测图像边缘（8个方向变换）。(Gaussian function through derivative edge detection in real terms is adjustable direction edge detection wavelet transform (change the direction of 8).)

用matlab实现的基于最大值对图像图形处理可实现多个图像(Based on the maximum value of image and graphics processing multiple images using matlab)

用减谱法进行语音增强，效果还不错。 读入语音，调整噪声水平即可。(Spectral method used by speech enhancement, the effect was not bad. Read into the voice, the noise level can be adjusted.)

说明：  vhdl 初学例程，对于初学者有很大的参考价值哦(VHDL beginner routines for beginners have great reference value oh)

PROGRAM IS USED FOR Interface matrix keyboard with 8051.

针对16阵元的均匀直线阵，使用MVDR算法和DREC两种方法分析方向图性能，DREC法进行特征值分解，大特征值对应的特征向量构成信号子空间。(For 16 array element uniform linear array, eigendecomposed MVDR algorithm using two methods and DREC pattern analysis performance, DREC method, large eigenvalues eigenvectors corresponding signal subspace.)

matlab用hough变换检测圆的程序，经过检测可以运行良好(matlab using hough transform circle detection procedure, after testing can run a good)

用有限差分方法求解波动方程，画出波场快照，模拟波在地下传播！(The wave equation by finite difference method, draw the wave field snapshot, simulate wave propagation in the underground!)
