应用于图像压缩的SPIHT算法代码，此代码的步骤很清晰，我自己加了很多注释，特别好理解。(SPIHT code which is used in image compression,with many notes of my own so really easy to understand.)

数字图像处理有关的论文，很优秀，很有指导意义的一篇论文。(Digital image processing the papers, very good, very instructive paper.)

1、可制作圆形、椭圆形、菱形、方形、三角形印章。 2、支持多种特效：翻转图形、透明处理、高斯模糊、亮度/对比度/饱和度/锐化/反相/海绵/陨化(磨砂)/浮雕等等。 3、可将制作好的印章保存至印章库。 4、支持1％－1000％比例缩放。 5、支持导出印章图片(透明图章使用GIF格式)。 6、支持预览/打印。(1, can be made round, oval, diamond, square, triangular seal. 2, supports a wide range of effects: flip graphics, transparent deal, Gaussian blur, brightness/contrast/Saturation/Sharpness/RP/sponge/meteorite of (Matte)/relief and so on. 3, can be saved to create a good seal of the Treasury seal. 4, in support of 1-1000 scaling. 5, support for export seal picture (stamp the use of transparent GIF format). 6, support for preview/print.)

pca-sift算法的实现，采用vc2008开发环境，进行开发，独立运行(pca-sift algorithm, using vc2008 development environment to develop, operate independently)

为了研究植物的生长规律，应用数字摄影图像处理法对山楂叶面积进行无损测量，该方法采用数码相机在田间获取山楂叶子的数字图像，对所拍图像进行背景去除、二值化及中值滤波处理，然后利用Matlab软件编程．快速计算出叶子的面积。把这一面积同常用的叶纸称重法所测面积进行比较．结果基本相同，由此可见，数字摄影图像法测量叶面积，具有简单、准确、方便快捷的特点．这对数字农业的植物信息快速采集和利用具有重要的意义。 ( In order to study the growth pattern of plants, the application of digital photography and image processing method for nondestructive measurement of hawthorn leaf area, this method using a digital camera to obtain digital images of hawthorn leaves in the field, on the film image background removal, binarization and medianfiltered, and then using the Matlab software programming. Quickly calculate the area of the leaves. This area with the common leaf paper weighing measured by the area to compare. The results are basically the same, shows, digital photographic images method to measure leaf area, with a simple, accurate, and convenient features. This rapid acquisition and use of digital agricultural plant is of great significance. In order to study the growth pattern of plants, the application of digital photography and image processing method for nondestructive measurement of hawthorn leaf area, this method using a digital camera to obtain digital images of )

说明：  matlab输入CAD图像文件，matlab中图形导入CAD，matlab与CAD互转(Matlab Input CAD Image File or graphics Import into CAD in matlab or matlab and CAD Interchange)

数字图像处理源代码绝对好用包括一些最基本了图像处理，例如增强(digital processing)

非常详细的一篇论文，仔细介绍了手指静脉识别的的全过程(A very detailed paper, carefully introduced the finger vein identification process)
