主成分分析算法（PCA），可用于降维，也可用于处理图像相关性问题，提取主成分，分析图像细节信息和主要成分，用于图像压缩也可以(Principal component analysis algorithm (PCA), can be used for dimensionality reduction, can also be used to process images related issues, extracted principal component analysis and main component of image detail information, to be used for image compression)

本代码为了检测哈弗曼编码后的图像压缩比，并且给出了哈夫曼的编码与解码(The code in order to detect Huffman encoded image compression ratio, and gives Huffman encoding and decoding)

关于指纹图像处理的有关论文资料，希望各位同仁多多 指教。(Fingerprint image on paper deal with the relevant information, I hope that Tongren exhibitions.)

NCUT切割，对源码进行了改进，改进后取消了只能压缩到160*160才能切割的限制(NCUT cutting, source code improvements, improved to cancel restrictions can only be compressed to 160* 160 to cut)

说明：  生成手写数字图片，一共提供了三种算法，example_1和example_2训练GAN来生成手写数字图片，搭建了一个简单的GAN的网络结构，example_3难度较大(There are three algorithms to generate handwritten digital pictures. Example_1 and example_2 train GAN to generate handwritten digital pictures, and build a simple network structure of GAN. Example_3 is more difficult.)

飞机弱小目标检测，利用固定权重，对背景进行全图重建，再利用残差图像，获得小目标的具体方位。(Aircraft small target detection, the use of fixed weights to rebuild the whole map background, and then use the residual image, obtain the specific location of small targets)

基于matlab的SSIM图像相似度评价算法实现(Matlab based on the the SSIM image similarity evaluation algorithm implementation)

结构张量来进行自适应正则化图像重建，单幅图像重建(Structure tensor adaptive regularized image reconstruction, a single image reconstruction)
