approche hybride firefly et k-mens pour la classification des image sat

matlab 的 Difference of Gaussian 算法实现，很常用的算法(matlab the Difference of Gaussian algorithm, it is commonly used algorithm)

基于MAP_MRF模型的SAR图像道路提取(Model-based SAR image MAP_MRF Road Extraction)

首先对指纹图像进行预处理，包括图像的分割，增强，二值化，细化。对细化后的图像进行特征点的提取，最后通过细节特征匹配完成指纹的识别。(Firstly, the fingerprint image is preprocessed, including image segmentation, enhancement, binarization and thinning. The refined image is extracted by feature points, and the fingerprint recognition is completed by minutiae feature matching.)

多基线干涉合成孔径雷达干涉条纹的获取，通过两幅单视复图像进行配准，获取干涉相位(Multi-baseline interferometric synthetic aperture radar interferometry fringes of the acquisition, through two single look complex image registration, access to intervention phase)

数字图像哈弗曼编码，包括压缩和解压。压缩比、信噪比(Encoded digital image Hafu Man)

说明：  PCA图像降噪新算法-LPG PCA，全名叫做Two-stage Image Denoising by Principal Component Analysis with Local Pixel Grouping。内含算法代码和数据集，均经本人实测，可进行灰度图像和RGB图像的降噪，且PSNR和SSIM指标明显好于小波滤波、K-SVD等经典算法。值得学习图像降噪的看看！(The new algorithm of PCA image denoising LPG PCA, full name is two stage image denoising by principal component analysis with local pixel grouping. The algorithm code and data set can be used to reduce the noise of gray image and RGB image, and the PSNR and SSIM are better than the classical algorithms such as wavelet filtering and K-SVD. It's worth learning about image denoising!)

数字信号处理实验，DCT图像压缩，内含有matlab实验m文件以及实验报告，供大家参考。(Digital signal processing experiment, DCT image compression, contains matlab experiment m documents and the experiment report for your reference.)

利用正交匹配跟踪原子库对信号进行稀疏分解程序(Using orthogonal matching pursuit atom libraries for signal sparse decomposition process)

说明：  对图像的傅里叶变换图像进行径向和角向频谱统计(Statistics of radial and angular spectrum of Fourier transform image)
