huffman-coding

此程序计算图像的七个不变矩，提取出图像的形状特征，可用于图像检索。(This procedure of calculating the image of seven invariant moments, the shape of extracted image features, can be used for image retrieval.)

六种图像增强的方法，线形反锐化掩膜方法，直方图均衡等。(6 kinds of image enhancement methods, linear unsharp mask method, such as histogram equalization.)

亚像素边缘检测，基于zernike 灰度矩，实现精度可达0.05个pixel(sub-pixel edge detect)

图像识别起步。裂纹图像二值化及其骨架提取算法.(Image recognition.Crack image binarization and skeleton extraction algorithm is proposed.)

利用jpda算法进行目标的跟踪仿真，给定目标的起始位置和运动速度，自动添加杂波，输出定位后结果(To utilize jpda algorithm for target tracking simulation, to the starting position and velocity of the target, and automatically add clutter, output positioning result)

说明：  sar图像去噪的几种新的方法，滤波效果明显，做毕设是在万方上找到的，分享一下(sar de-noising )

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!)

该程序是发表在IEEE上的经典直线提取论文“Extracting Straight Lines”的源代码实现，对计算机视觉、模式识别和信息提取等领域的科学研究人员具有极其重要的参看意义。建议下载学习和适用。(The program is published in the IEEE paper on the classic straight-line extraction " Extracting Straight Lines" the source code implementation of computer vision, pattern recognition and information extraction and other areas of scientific researchers see an extremely important significance. Recommended to download to learn and to apply.)

求二维图像的极大值点与极小值点，很好用，希望对大家有帮助(image maximum points and minimum points, very useful)
