数字图像压缩方向一些经典压缩方法的matlab程序实现(Digital image compression direction, some classic compression methods, matlab program implementation)

此程序是基于灰度共生矩阵的图像纹理特征提取算法，它进行了四个方向上的灰度共生矩阵的计算，从而得出他们的纹理特征向量，再求均值，使计算进度大幅度提高(This program is based on the GLCM texture feature extraction algorithm, which was four directions GLCM calculation to arrive at their texture feature vector, and then seek means to significantly increase computing progress)

语音信号小波去噪 在小波基 db3 下进行一维离散小波反变换 对输出信号抽样点值进行归一化处理(Speech signal wavelet de-noising in wavelet bases ' db3' one-dimensional discrete wavelet transform on the output signal sample point value normalization)

说明：  通过matlab，可以快速得到图像的特定区域的灰度值，里面也有一些解释(Through MATLAB, we can quickly get the gray value of the specific region of the image, which also has some explanations)

对一维信号的过采样函数，采用SINC插值的方法，可以使输出信号更加平滑。函数用法有说明，并附有简单程序进行验证说明。希望对有需要朋友有用! 有问题欢迎留言交流！(For the oversampling function of one-dimensional signal, SINC interpolation method is used. The usage of the function is explained, and a simple program is attached to verify the explanation.)

此程序计算的是两幅图像的峰值信噪比，运行流畅(This program calculates the peak signal to noise ratio of the two images, run smoothly)

用奇异值分解的方法实现图像压缩，有助于初学者了解奇异值分解的应用(Using singular value decomposition method to achieve image compression will help beginners understand the application of singular value decomposition)

双目立体视觉，基于matlab，适合新手看看，比较简单(Stereoscopic vision, based on matlab, suitable for novice to see)
