用八叉树法对逆向工程得到扫描的三维实体模型图像处理，实现了对大量点云数据进行三维网格构建。(Octree method of reverse engineering can be scanned 3D solid model of image processing, realize the construct 3D mesh of a lot of point cloud data.)

好东东哦，希望大家来下载，是 我们本科毕业设计论文成果，基于dct域的数字水印技术

此程序为用于jpeg2000中的小波零树压缩编码，它采用了小波零树编码原理，利用了小波系数之间的关系(this procedure for the jpeg2000 EZW coding, It uses wavelet zerotree coding theory, the use of wavelet coefficients of the relationship between)

图形密码源码程序，例程结合易语言特殊功能支持库，调用API函数判断图形图像的点击顺序。(Graphics password source programs, routines combined with special features easy language support library , call the API function to determine whether a graphic image click sequence.)

利用索贝尔算子两种模板提取图像梯度，幅度选取分别利用欧式距离、城区距离和棋盘距离。(Using two templates of Sobel operator to extract the gradient of a image. Magnitude was selected by using Euclidean distance, city distance and chessboard distance.)

约束最小二乘法图像复原代码，直接上图片就可以使用的。(Constrained least squares image restoration code directly on the image to be used.)

图像格式转换例程源码，程序主要结合易语言图像格式转换支持库，可以将某些图象文件的格式转换到其它图象文件的格式(Image format conversion routines source, the program mainly with easy language support library image format conversion , you can convert some of the image file format to other image file format)

计算色素占比，能够自动计算各种颜色的占比。省时省力。(Calculate the proportion of pigment, can automatically calculate the proportion of various colors. Saving time.)

小波均匀量化huffman熵编码图像压缩程序：分析对象Lena.bmp(Uniform quantization of wavelet image compression huffman entropy coding procedure: analysis of object Lena.bmp)

说明：  使用sift进行的图像拼接，matlab语言实现(Image mosaic using sift)
