compression

说明：  图像预处理以及提取图像的Tamura 纹理特征(Image preprocessing and Tamura texture feature extraction)

说明：  高光谱图像数据集，Pavia University scene该数据是高光谱图像处理中常用的数据之一，对高光谱图像算法性能的验证具有通用性(Hyperspectral image data set, Pavia University scene This data is one of the commonly used data in hyperspectral image processing, and it has universality to verify the performance of hyperspectral image algorithm)

说明：  基于matlab的语音信号处理快速傅里叶变换程序(Fast Fourier Transform Program for Speech Signal Processing Based on MATLAB)

python实现人脸识别，通过pca进行降维然后使用SVM算法进行分类(Python realizes face recognition, dimensionality reduction through pca and classification by SVM algorithm)

将.rgb格式的图像转换为.yuv格式的图像,.yuv格式的图像按4：2：0采样(will. Rgb format conversion of images. YUV format images. YUV format image with 4:2:0 sampling)

C++调试的背景的颜色改为比较对眼睛好看的颜色呢(C++ debugging change the color of the background of relatively good-looking colors for the eyes)

对Lorenz系统混沌吸引子的仿真，直接能用。(The simulation of the chaotic attractor of the Lorenz system can be used directly.)

主要适用于图像增强的客观质量评价，效果比较好；其实熵值就是求图像的相似度(Mainly applied to the objective of image quality evaluation, the effect is better; In fact, the entropy is to find the image similarity)

说明：  代码包含多种图像去雾质量评价标准，PSNR，彩色图像信息熵，WPSNR等，MATLAB可直接使用(Code contains a variety of image defogging quality evaluation criteria, PSNR, color image information entropy, WPSNR, etc., which can be directly used by MATLAB.)

说明：  MATLAB源代码实现BP人工神经网络算法。(BP Neural Network based on MATLAB. )
