extract exif from jpeg image

地理信息系统中矢量数据的三维可视化技术(IDL)-GIS vector data visualization technology (IDL)

自己用C语言编写的中点画圆算法，根据用户输入的圆心坐标和半径画出相应的圆形。-own use C language prepared by the midpoint drawcircle algorithm, According to user input center coordinates and radius of the circle corresponding paint.

基于sift的图像复制粘贴篡改检测方法，首先提取出sift特征，这里提取的sift特征是用c++代码提取的，然后进行g2nn匹配和 凝聚层次聚类 ，最后根据仿射变换参数标出篡改区域。并用连线的方式将真实区域和复制粘贴篡改区域标记出来。

图形中，视口跟窗口的变换算法，比较基础的-Graphics, depending on the mouth with the window transform algorithm, the basis of comparison

C语言的体系，大量使用指针运算速度可以保证，内含先进的多种插值算法。 另外独有的支持meta exif信息的读取。该库最大的特点就是比较简练，只把重点放在对各种格式图像的读取写入支持上，没有显示部分，实际编程的时候还是需要调用API函数进行显示。 -FreeImage is an Open Source library project for developers who would like to support popular graphics image formats like PNG, BMP, JPEG, TIFF and others as needed by today s multimedia applications. FreeImage is easy to use, fast, multithreading safe, compatible with all 32-bit versions of Windows, and cross-platform (works both with Linux and Mac OS X).
