最新的用matlab实现的ＳＰＩＨＴ算法，实现对图像的高性能压缩。(Matlab using the latest achievement of SPIHT, the realization of high-performance image compression.)

CxImage是一款免费的、开源的、功能强大的图形处理库。 跨平台，支持windows、linux等；支持BMP、GIF、ICO、TGA、JPEG、PCX、PNG、TIFF、MNG、RAS等多种图像格式；支持格式转换、图像处理、几何变换等；最重要的是使用非常简单。此为VC6修正版(CxImage is a C++ image processing library. It can load, save, display, transform images in a very simple and fast way, with transparency, multiple layers and selections, support for BMP GIF JPG PNG MNG TIF ICO TGA PCX J2K JBG RAS PNM RAW PSD.)

说明：  QR二维码识别中在对图像预处理后最重要的一步就是要进行定位，QR二维码中有三个位置探测图形，通过扫描其特征便可以进行精细定位，提出了一种新的算法用于筛选候选点。(In QR code recognition, the most important step after image preprocessing is to locate. There are three position detection patterns in QR code, which can be precisely located by scanning its features. A new algorithm is proposed to screen candidate points.)

用c语言编写的数字图像处理程序，图像读取，图像增强，图像复原，傅里叶变换，离散余弦变换都有(With the c language digital image processing, image scanning, image enhancement, image restoration, Fourier transform, discrete cosine transform has)

利用块匹配稳像算法实现视频去抖动。 主程序入口位于shakeproof.m(shakeproof.m main function. emba.m exhaustive macro block matching algorithm. splitmv.m split mv field into backgroud and foreground. hist2d.m 2d histogram function.)

方向梯度直方图的全部代码，广泛应用于行人检测行人检测(Histogram of Oriented Gradients code Pedestrian Detection)

说明：  采用霍夫曼技术实现压缩图像的重建，代码很详细，很不错。(Using Hoffman technology to achieve compressed image reconstruction, the code is very detailed, very good.)

在对散乱点云进行三维重建时，许多算法都需要求点云的法矢并保证所有法矢的方向一致向外。本程序就是对点云数据求法矢和方向调整，包含文件输入输出的完整程序。(Scattered normals strike and reorientation)

matlab检测圆心程序，基于HOUGH，附测试图像。(Detect matlab center procedures, based on HOUGH, attached to the test image.)

自己编写图像平滑算法：均值滤波和中值滤波，设置不同的均值滤波模板，以得到最好的图像输出结果。(I have written the image smoothing algorithm: mean filter and median filter, mean filter set different templates to get the best image output.)
